BuddyPress members page 'Alphabetical' and 'Newest Registered' not working

Since the latest BuddyPress update 1.5.4 the members page only shows the ‘Last Active’ list. The drop down menu for ‘Alphabetical’ and ‘Newest Registered’ does nothing.

The ‘Search Members’ works just fine.

I am using the Business Portfolio theme with the membership plugin.

Has anyone else experienced this issue?
