Hello :3
No worry the solution is easy :)
Go to MainMenu → Buttons → Controls → Controls buttons mechanics → Create buttons text → change the number 11 in the condition to 12 or to the number of the buttons you have, by default they are 11, if you added one new button then make it 12, if you added 2 new buttons then make it 13...etc, this should fix the issue :3
Sure when your game is out i can take a look :D
