Button Trouble

Im having an issue with my buttons. Im currently using the new style of glide and I have two buttons to join members. When the button action is set to edit screen the button disappears but when its on form screen the button shows. I took away the Role column because it wasn’t allowing me to set the column as needed when joining a member. made my own column as user type that’s when the madness came about. Can someone please explain to me how to get this to be correct. thanks, in advance!
