Missing controls - hotbar in battle

[Pilda]

I just tried the game Vampyr and there is a bug when the numbers don't work for keyboards which are not english. People say it is a known bug of Unreal Engine. It only work if the keyboard is switched to EN locale which is very annoying. Is it this bug too? Could you please fix it?

Each skill in the battle hotbar has a number but they are not executable with numerical buttons as one would expect. Could you please add support of key binding for the slots? Or is it a bug and it is supposed to work as I suggested?
