Can't use number keybinds

I’m not sure what I did. But for some reason now I can’t use my number keybinds anymore (1 for health and 2 for minion stance). I checked the bindings and they’re still there. I tried removing the binding and re-binding it, but only the removal worked. When I tried to re-bind, it wouldn’t register. It’s weird because it’s only the number keys that have this problem. But I can still type numbers in chat.
