Advanced_Forum Permissions Help - Delete Own Topic Not Working

I am using advanced_forum at http://www.lonestarfishing.org .

I have permissions set to allow users to:

Create Forum Topics
Edit Own Forum Topics
Delete Own Forum Topics

See permissions here: http://www.lonestarfishing.org/images/permissions.jpg

Members that post replies are not able to delete their own replies/topics. The can Edit, Reply, and Quote but the delete button is not available unless I give them "administer_comments" permission, which gives them the ability to delete other's Replies.

What am I missing here? Shouldn't members be able to delete their own replies to a Topic?

Thanks in advance
