Mail shows wrong VIP / Stars

Hello Community,

i have a problem with my iOS Mail App on iPhone and iPad. I had some friends in the VIP list. My iPhone and iPad marked the mails from these people with a “Star” in the overview. But my problem is that some other Mails / Newsletter are marked with the star too. I deleted all people in my VIP list, deactivated the Mail in the iCloud settings and rebooted my iPhone and iPad again. But the problem doesn’t fixed it… the wrong mails are marked.

The Mail App shows only on iPhone and iPad the wrong VIPs. On iCloud.com and my MacBook the Mails haven’t the wrong marked Stars...

What i have to do?

Thx a lot for helping!

Robert
