Discord Sucks and this is a Bug Report

I purchased a license for Monarch. I’ve tried to set the “Open Monarch Short Cut" to “⌃⇧M" but I am unable to save this. I have “⌥ " (option space) set to Alfred, and not it invokes both Alfred and Monarch, but subsequent keystrokes go to Alfred.

How can I set the keyboard shortcut for Monarch?

Thanks,
