Hi, like the title says, I'm not sure if I'm just missing something obvious or if it's to do with a recent update?

My keyboard has assignable "G Keys" that I've been using as my Hotkeys for my Monitor Configuration Profiles. I used a combination of Autohotkey and the proprietary Corsair software for my keyboard to set "G1" to F14 and "G2" to F15, so I can swap between the monitor profiles seamlessly. This was initially done about 6-8 months ago.
I wanted to add a new Monitor Profile, so I went through and mapped my "G3" key to be F16, but when I go to set the Hotkey in Display Fusion, it doesn't recognise it at all. Windows (10) is definitely recognizing it as the F16 key, but even if I remap a "normal" key in Autohotkey, the Hotkey menu in DF doesn't seem to recognize the new mapping (eg. if I remap F5 to be F16 in autohotkey, DF still reads the keystroke as F5 in the Hotkey menu)
I'm sure the above was how I set it up before and it worked flawlessly. Should I be doing something differently now?

Thanks in advance for any help!
