DropDown Menu static if I enter as a registered user

Hello. Sorry for my English, I'm using Google translator ...
The menu "DropDown" works fine but stops working when I enter as a registered user. So is static showing all lower levels.

I discovered that it is a conflict with BT Login module. I'll see if I can find out what causes this module property error with drop-down menu.
If units. can guide me where to look, be grateful.
