I’m registered in two squads in a match

I accidentally registered in two squads in a match. How do I get out of a squad without canceling the match?

After checking your account and your inbox the reason you have two squad spots is that you have registered for the match twice. Once Mon, May 6, 2024 1:07 AM and a second time Mon, May 6, 2024 11:40 PM.
You will have to look at your inbox and choose a registration to stick with while asking to be withdrawn from another.
