Email address assigned to the Apple Wallet on my account keeps changing

OMG the last hint - BINGO.

My default language is polish and this is not exactly the same path, Its not exactly shipping Address, but underneath is another bar- Email field, so slightly different. Sorry for miss translation. So for me it was something like that:

Settings->Wallet and ApplePay->ApplePay default settings->and on this screen you have option fields like - default card, shipping address, email and phone...

AND ONLY HERE in the whole apple ecosystem, only here - you can actually see whole history(?) of emails - click on email and then - you see the whole list of emails WITH EDIT option. This precious edit option which you miss on MacBook! From this screen finally I was able to delete my wife email address and leave only mine.

The mistery for me is only one thing, why AppleWallet on ma MacBook was picking all the time my wife email as default even when I deliberately set mine (and for example iOS didn't try to change it on my iPhone, - only macOS on MacBook). Anyway, I deleted her email so that stupid macOS do not have it anymore in the pool. And why her email was even visible on my user account. My wife is a total noob I have to explain her everything there is no way she could type anything on my account.

I don't get it, but it is a scar on apple ecosystem which is great and I love it, but this issue was mind-blowing.

Jeff - thank you 👍

She is in my family group. But we do not use the same apple account. She has her own (for iPhone and the same on MacBook) And I have my separate Apple ID on my iPhone - which I use on the same MacBook. So we use the same laptop but each of us on their own account.

Im the administrator and owner of the family group.

yes of course, is there another way? I have to log out, so she can log in to her account.

I have to say… I'm stunned by this because I can't explain it logically. Especially since I recently reinstalled the system, carefully and slowly configuring every detail. Finally, I added my wife's user account using her Apple ID, everything as the book says. When I noticed that for some reason the system had inserted my wife's email address into my wallet, my eyes popped out of my head. And when I started changing it to my email address and the system corrected it back to my wife's, I thought I was going to fall out of my chair.

I have no idea even how to correct this. Where to look 😒

When I was searching for an answer on google, - have found this tip. I’ve checked what you wrote. Everything is filled correctly on my contact card. Only my @ address. I’ve heard about safari cache which is absurd but I’ve cleaned cache anyway.

I posted here because I ran out of ideas from Google.

I have iphone, my wife as well, and I have a macbook Air. That’s it.

I have to say, that It’s really, really bizarre that data from my apple wallet is changing dynamically based on what @ is on my contact card or safari cache, or anything else than datapoint there BY MYSELF. Can you imagine apple wallet can change your credit card number, because system saw some random numbers somewhere on my contact card, or change my Apple Wallet location address because system took some adress I was typing for some other purpose?

Ok, firstly thank you for your time, I appreciate your effort.

Let me be more specific. In your macbook settings You have Wallet, and on Wallet card you can add credit card and below you have additional info about your home adress credit card type, and - email adress. And this field of email adress is the source of my frustration.

On my macbook I have my account (my apple ID) the same account I’m signed in on my iphone. I’m the main user and Administrator as well.

And I added on my macbook- second account - my wife apple id account (she is already on my family group)

Just added another user In this case my wife apple ID…. That’s it. Nothing more, no other devices, no messing around with strange settings. Simple stuff.

I would like to clear some cache maybe something is refreshing wrongly, but have no idea where to lookup
