MyBB Community Forums

I want moderators in my forum to reach moderator logs, only for forums they are added as moderator to.

There are two options:

1. When you assign a moderator, it asks if this moderator should be able to see modlogs for this forum.
   
2. For each usergroup there's an option "Can view moderator logs"
   

In usergroup (in option 1) when you activate "Can view moderator logs", those users see modlogs of all forums (entire site), when you take it away - they see nothing, even if you give them access to logs (in option 2).

Is it a general issue? if not - what am I doing wrong?
