When I apply the filter "4" to the "name" column on the create profile page, everything works fine. If I remove the filter it works fine. If I try to apply the filter again, it doesn't work. If I change the filter to something else, it works. If I change back to the 4, then it works.
Another clue on this--if I backspace over the filter when entered the second time and then re-type it, it works. In terms of the example above. When I clear the filter "4" using the "x" to clear it, it seems to clear--all the TRs are displayed again--but when I re-enter "4" in the filter field nothing happens. If I then backspace over the "4" I just entered and retype it, the filter is applied!
It occurs to me that the easiest solution to this might be to remove the "x" on the filter boxes. They do not appear on all the boxes so they are inconsistent anyway and you can achieve the same thing by using the delete or backspace key.
