Bug: Ctrl+Z turns the brush into a hand tool

Every time I undo while drawing in Toon Boom, the brush I am using turns into a hand tool and I manually have to select the brush tool again to start drawing. I’ve never had this issue come up before in other drawing programs. I tried to find if it was something wrong with my shortcuts but I couldn’t see anything that might cause it, plus I am using the default Toon Boom settings. Any reason why this issue might be happening?

Info on what OS you are using and Harmony version/build would help.

If you are on Windows 10 under Setting check Time & Language>Language and that everything is correct. Also look under Ease of Access>Interaction>Keyboard checking Sticky Keys, filter keys etc.
