Hello there, I was annoyed by the same problem and Investigated it.
The Problem seems to be that the search function (for player Count selection) requires an Integer Value but gets a Float value due to the way the Selection slider is implemented. If you want to circumvent this problem tick the box "Display search query" then select the desired number of players. You will now see this command appearing in the query "(latestVersion.maxPlayers=ge="4.0";latestVersion.maxPlayers=le="10.0")" now simply remove the ".0" behind your desired Player numbers and hit search.

I hope this might have been helpful to you.
Best Regards Jugger
