Self cast doesn't really work anymore

Alt+R, Alt+F doesn’t work for me for a while in the game.
They work fine everywhere else.
Also, Alt+W works.

I don’t know whether an actual gaming keyboard is required for the game, but …

Anyway. Super weird. Also lost a few matches due to it - failing to place maching guns or self cast ult.

I don’t know how it was, but self cast seems to be replaced by specific cast options, and there is no option for self cast map mechanic ability. But the others are there.
