Members not showing in BuddyPress Members Directory

Hi,

Not all Members are showing in the BuddyPress members Directory.

At the time of writing there are 13 users (as displayed in the Dashboard > Users > All Users). However at frontend the Members Directory only shows four Members:

Will it be a case where some Members do not activate their account after registration? I am trying to find out from them.

I must say that all the test members I have registered they all show up no problem at all.

I would be grateful for your advise.

Best regards,

Tony
