"o", "m" keys not working

I am using Better Snap Tool 1.9.5 and Macbook Pro 2019, and Big Sur 11.2. When I activate the tool, I cannot input "o" and "m" key. Simply cannot input the characters. Does anybody experience the same?
How can I fix it?


most likely you have accidentally assigned them as shortcut to some positions in the BetterSnapTool preferences, is that possible?
