MW2 Lobby Tools - All Players on Yellow Team on Startup

(big apologies for posting this thread yesterday in the wrong spot, meant Help Request, not just Help)

Hello everyone. I yesterday made a thread asking how to Inject, and now I know how to do that, but since I have started using MW2 Lobby Tools, I cannot seem to set up the lobby appropriately to put players on teams automatically. Everyone who joins in after I start the game, however, join in on normal teams (Rangers, OpFor, etc.), but those who are in the lobby before I force launch are set onto the FFA side basically, the Yellow tag. One way to fix this is to kick the people who are already in and hope that they come back, but that's not always the best when you're attempting to fill up your lobby. This isn't exactly a big deal on FFA of course, as everyone against each other to begin with, but on team game modes, it is hard to distinguish who is on your team and who is not. Although it shows no one as on your team (if you are part of the FFA Yellow tag or on your own on a specific team by yourself (the only person on the OpFor team for example)), you can still not kill people who are on the same team, as in you cannot kill another TF141 although it says you're both enemies.

Hopefully someone knows how to fix this, as I am a huge fan of MW2 and would love to make lots of lobbies for people to enjoy. If it matters (as I've seen people saying stuff about what OS they use), I am using Windows 10 Home Edition (free upgrade from owning Windows 7).
