Notification on iOS (wrong numbers of notifiaction in the red bubble)

### Steps to reproduce

I have the problem that every message that the Element Messenger receives shows a three in the notification bubble instead of a one. I have now tried all possible notification options both in the iOS app and directly in the browser, but all without success. Does anyone of you have an idea how I can solve the problem?
