My DDO guild page features wrong leader

[Dissindra]

on my guild page in My DDO, the guild roster is led by the wrong leader. In the "Guild Profile" window, there is the right leader written; only in the "Guild Roster" is shown another one, the wrong one ....
I could edit nearly everthing else, but how can I tell that page, that another char is the leader (for around 5 months now, we had a change at that time)?

like in my own player page, I may mark my primary character in a list of chars; can't I mark the leader of my guild in a similar way? or where does that guild roster gets the information from, that THIS specific char was the leader?
