Templates drop down not showing on frontend registration

Hi Guys,

I'm using "New Blog Templates", I can create blogs from the backend selecting the template I want without any problem,
but when I create a new user from the frontend the drop down menu with templates selection is not showing.
So I can't give my users the choice of the templates :slight_frown:

I'm using BuddyPress, Mutli-Domains, Domain Mapping, Default Theme (disabled).
Might be there a conflict ?
