How to disable apple sandbox wallet

Hey! I am facing a problem - can't add real cards for my Apple Wallet. I used my account some time ago to test Apple Pay on the web, so I turned on Sandbox. Now, on iPhone, on wallet I can see the sandbox label.

In the attachment is an error and a screenshot of the wallet. Also had a conversation with two bank support, and they assured me that from their side, they would not even receive request to connect with Apple Wallet from this phone. On MacBook I got the same error
