I built a few kits and have some basic electronics knowledge, so a buddy of mine brought me this. Says the left foot switch popped off, but he was able to pop it back on, it's just didn't go all the way back on. See the photo for reference, the left foot switch has a gap between the top and post. My question, is this just cosmetic, or a sign of deeper issues with the foot switch? Either way, does anyone know how to best fix it?

Thanks!
