When I’m playing Local Splitscreen in Minecraft, I can’t use Character Creator when another player is using it because my screen mimics the other player’s screen

For Example: I’m using Character Creator, then another player in Splitscreen uses it, when they press the “Base” option, my screen goes to base too and I cannot click anything, and when they leave Character Creator, my screen goes blank and the options on Character Creator is gone.

Note: This happens in all  game modes.
