Pokémon selection screen bug when pressing ENTER and SPACE simultaneously

[SnowCharmQ]

In the SelectStarterPhase, if I have already selected one/two Pokémon(s) and press the ENTER key to start the game, while also quickly pressing the SPACE key, the following situation occurs. At this point, I can still enter the game, but the Pokémon selection options remain displayed on the screen and cannot be removed.
