2 Player game on one keyboard not letting second player jump using blueprint interfaces

Hey so I made a game where 2 players can be controlled using the same keyboard using blueprint interfaces. The moving works fine but I cannot get the second player to jump. The moving works by having the second players controls in the first player and then using the interface to transfer the input and axis onto the second players blueprint. With jumping its not working because I keep getting the error no matter what I do with the interface of “Cannot override ‘interfacename::JUMP’ at which was declared in a parent with a different signature” I do not know how to fix this. Any help appreciated.
