BuddyPress.org

I have more than 13.000 users in my Buddypress.
But my search directory member search has a big issue:
If you search for users and filter them usually you get more pages right?
On the first page the search filter is correct: you get all the results you were looking for.

BUT

when you move on to the next pages, suddently all the filters are gone.
You will not see the results anymore. In that way you cannot find ALL the users you were looking for.

Example:
I make a selection off all users from the UK.
After clicking to page 2, I see also users from the rest of the world.
Where are the remaining UK-users??

This is very important to me. Please help me!
