@denisdifazio which keyboard layout are you using? I think if you're not using English US, what's happening is that the right Alt key on your keyboard (also known as AltGr if the keyboard layout is not En-US) is actually Ctrl+Alt, so when you press the AltGr key with the above remappings, it sends Ctrl+Backspace, so the whole word gets deleted. You can confirm this by opening the Remap shortcut window and click 'Type' and press the right Alt button, it should show up as Ctrl+Alt.
As of now we don't support remapping multiple modifiers (Ctrl+Alt) to a key/shortcut. but we plan to support this in the future.

Thank you @arjunbalgovind for the clarification! I didn't know about this behaviour of AltGr. As you suspected, I am not using English US keyboard layout. I am using Brazil ABNT2.
I am closing this issue for now.
