Contacts "corrupted"

This apparently is happening when you add a work email address or a Gmail address after upgrading your phone and accidentally leave contacts syncing on for the new addresses. I typically only sync my contacts to my main iCloud address and whenever I add a new work email or other email I never select the option to sync those contacts, I believe the culprit is a third-party Gmail account or Microsoft account that I added for work that is trying to fill some things in “smart way “but instead of actually filling out the incorrectly, we are seeing the token that they use in programming to typically dynamically show that thing such as an email or location, etc. Unfortunately I verified that I did have contacts synced from Microsoft and a Gmail account which I don’t need so I turned that off under contacts and I had to go in and manually fix those contacts that were corrupted but on the positive side it gave me an opportunity to clean out the ones I don’t need anymore and it’s a lot easier if you do it on your Mac because it syncs back to your phone. Another note is that you can search for the corrupted strings of text and it will bring up any contacts that have that so it makes it a little easier to sift through the bad ones. I hope this helps.
