Incorrect Apple ID Displayed in App Store Profile

Hi,

I'm experiencing a strange issue in the App Store. When I open the App Store, click on my profile, and view my account details (name, Apple ID, purchase history, etc.), my Apple ID is displayed incorrectly.

My actual Apple ID starts with "firstnamelastname", but it appears as "firstnameRandomName" in the profile section. Interestingly, after updating to iOS 18.3.2, it initially displayed correctly, but later reverted to the incorrect version. I’m unsure why this is happening, but I wanted to bring it to your attention. Since I can't attach a screenshot here, I hope this description helps. Has anyone else experienced this, or is there any known fix for it?

Thank you!
