Help - 3rd Person Game Controller, my map spawns a new player, seems to ignore the one I placed

I’m using the included 3rd Person Controller in my project, and when I press play I can see my player in the map, but it seems to spawn another player automatically. I’ve been referencing the 3rd person example project, which this is built off of - it’s just a separate level - but I can’t find the issue. I’m using the default 3rd Person Gamemode blueprint in the World Settings. I’m sorry if this is kind of vague, I don’t really know what other information I can provide, it’s just ignoring the controller that I place down, and spawning a second one.

place a playerstart on the map, instead of the pawn.
