Hotkeys from [y] and [u] not working together

[Stone Dog]

As per title:

Assigning an hotkey number to an action from the [y]use menu will cancel the hotkeys already defined from the [u]se skill menu, and vice-versa.

I don't understand what the problem is.

A key like 5 can only mean one thing when pressed in game. Assigning it in the [y] menu should clear it from the [u] menu.

Needs description clearly explaining the problem.
