"Play again" not working on blind pick games

I play blind pick with my brother when we want to try out different champions and don't want to wait 5 years to get into a game. Anyway, when the game is over and we want to play again, I'll hit play again(I'm always the person who invites), it'll send me to making a custom game. It's very frustrating and has been happening for a long time.

If you need any more information, I'm willing to provide it.
