So I tried to set "bottom left action bar 1" to be used when hitting the key "R", and the R didn't show up on the action button, no visual at all.
Though when I tried to set "bottom left 2" to "V", it would show up. So I tried to then see if it was this first button that wasn't working or not, and put V onto it instead of R and it didn't show up, but "bottom left 2" still had V showing up on that button despite me unbinding it!
Anyone else having similar issues?
