As designed Alert notification bubble showed incorrect number


Well-known member
Hi, I am visiting xenforo forums after quite a while. On logging in, it showed me that I have 21 pending notifications within the red bubble above Alerts tab. When I opened it, I can only see 4 alerts starting from April 12 till today. The rest where probably deleted or something. Anyway, the alert bubble showed me an incorrect number on logging in. Is this normal?
