visitor messages can be edited and deleted by all registered users?
 

When members on my board visit someone else's profile, they have the ability to edit and delete all the visitor messages in that profile. I have both the editing and delete options marked "no" in the membergroup permissions, plus aren't those just supposed to apply to a member's own posts and own profile? Is there some other setting I need to correct to make it so that registered users cannot edit and delete posts in other members' profiles?
