ctrl alt shortcuts not working

I have a series of keyboard shortcuts that I am accustomed to, and wanted to reprogram some of them into scrivener. I’ve programmed the footnote shortcut to be ctrl alt f and the comment to be ctrl alt c, but although in the list of shortcuts they are listed as such, they are not functioning in the program. I get a capital F or a capital C if I press the shortcut. Any suggestions?

On another note, is there a way to shortcut to the function of converting in-text footnotes and comments to inspector notes and comments? I couldn’t find one and it would save a lot of clicking.
