BuddyPress.org

Just some observations

1. ‘my members’ isn’t the same as ‘my-members’
2. <?php echo 'is_page()='.is_page().'<br>'; ?> – why are you doing this?

I don’t know about you, but to me this seems like a bug in buddypress

There may well be a bug in BuddyPress – but I can’t tell that from the code and info you’ve posted.
