The filter functionality for community game servers is not optimal and sometimes does not even work. I just have stopped using it and just rely on my eyes instead.

Bug report:
The most obvious bug I have encountered is that the filter of active players on a server does not work. It does not matter if I set it to at least 1 or more players. It will show servers with no activity regardless. This was not a problem until the latest patch.

Suggestion for improvement:

Make filter options on everything. Including game mode, map, etc...
