Wrong number count. No emails but 16 shown in the count

[mastix]

In my spam folder I have 16 messages but when I go there 0 messages are shown. I have deleted everything. Nothing is on my server in the spam folder. I tried to repair the folder but that 16 wrong number still shows. Do not know what to do anymore to try to fix this. I am on latest version on win 11
