2 canvases working weird with buttons

I have a game with 2 canvases. One for when the player is moving around normally, and one for battles. The battle canvas is working fine, but when i add buttons to the player canvas i get weird interactions. It seems like the buttons on the battle canvas gets activated when i click on the player canvas, and most of the screen for the player doesnt even let me click the buttons.

Is it just me having troubble with buttons?
