BuddyPress.org

I have a problem with the private msg tool from buddypress.

I write a User a private Message, and the System puts randomly another user to the conversation and “deleted user”.

So I write a Private Message to User A and after “send” this comes up:

“Conversation between User C, Deleted User, User A und you.”

I write another Private Message to User F and after:

“Conversation between User D, Deleted User, User F und you.”

So I don’t know what happened and need your help, please.
