Hello! this is a split screen issue due to where the edges of the screen are set, If you've needed to change your safe region to match your screen, then there is a bug which is moving the cursor for player 1 when the bottom edge is changed, its moving both players up off the bottom edge instead of just the bottom player. If you're able to use split screen without the safe region being changed, or try changing split screen to Side-by-side instead of top-and-bottom it might fix this issue until the next update is released
