[Plugin Mingle Forum] Moderators Issue

Hi everybody, i’ve a problem with Mingle Forum.
We are 3 wp administrator and in mingle forum there are 6 sections and i want to moderatore only 1 section but automatically set me like a global moderator.
i see that my account can moderate 6 sections, i uncheck 5 of these ones, then update but there’s no differences, i’m always a moderator of all sections.
What can i do? Thank you and sorry for my english ??
