Menu settings in BuddyPress Daily notcorrect ?

In the "BuddyPress Daily" you should be able to replace the default menu with a custom menue.
"Your theme supports 1 menu. Select which menu you would like to use."
Primary Navigation:
Here I choose my custom menue.

Nevertheless in the theme the default menu is maintained, and the custom menu is added below it.
When I set a custom menu as primary navigation the original mnue should be replaced, or do I get something wrong here ?

If the theme is working fine, how do I get rid of the originl menu and use only my custom menu ?
