Ok, figured that out as well
. Nevermind
If anyone else is doing this for the first time and needed to know... To get players to show up properly... Make sure before they start, they have a login and password inside the game (under the game tab). As long as they use that login before they start the match it will update only that players stats.
As far as deleting a player from UTstatsDB. Login to the database (I used navicat since I use that for wow server stuff already anyway). You can remove players, stats, whatever is on the DB in there.
Most of you probably knew this already, sorry for the dumb questions, was first time doing this hehe. Server is running great now though!
