Problem creating control groups with extra mouse buttons

I tried to make and select control groups by using extra mouse buttons, in the hotkey menu the command is recognized, as seen in this image:

but when playing the game the command does not create a new group.

Nevertheless, if i create a group by using ctrl+1 for insntance, I can select it with the mouse button without any problem

On the same note, im having issues when creating a grup with the key that is beside the 1 key.

As you can see in the image, when i asign the ctrl+GRAVE key as a hotkey, the hotkey bellow that one changes (note as just beside the ctrl+GRAVE key, the hotkey is `1 instead of 1, that changed on its own when i changed the create group #20 hotkey).

Then, when i try to asign the GRAVE key to the select group #20, it does not recognize the key.
