How to fix a kickstand that slide?

This is the kickstand of my folding bike, and since the day I bought it, the kickstand just don’t stay in place. It move around the bolt a tiny little bit, and from time to time it touches the crank arm when closed making noise while pedaling, and don’t sustain the bike as good as is suppose to do when opened. I temporary fix it by kicking it with the foot to push closer to the wheel. I tried to put a piece of rubber in between (you can spot it in the picture) to increase the friction between the plates, but it still moves around, no matter how tight is the bolt. There is something I can do about it?
Thank you!
