XF 1.5 Wrong number of posts


Active member
If I have posts in a thread and if I hover on my avatar I will see this message (You have posted X message in this thread) like this:


In my forum the number of messages is showing wrong.
For example, I have 90 messages in a thread and it is showing (You have posted 1 message)
Another thread I have 40 messages and it is showing (you have posted 2 messages)

I imported around 1M posts from vBulletin and I updated all the counters. Is there anything I need to do?
