Flydigi Apex 5 extra buttons not registering

### Is there an existing issue for this?

- [x] I searched the existing issues and did not find anything similar.

### Current Behavior

The Flydigi Apex 5's 6 extra buttons show up on the list and are programmable but aren't actually recognized when pressed. Happens in 3.5.0 and 3.5.1. (Doesn't work when ran as normal or administrator)
Also dark mode windows theme isn't recognized in 5.1 when it is in 5.0
Currently using 5.0 as that has a working darkmode and bugged behavior is the same across both versions.

### Expected Behavior

Program recognizing when extra paddle/button is pressed.
And dark system theme carrying over to program in 3.5.1

### Steps To Reproduce

1. connect apex 5
2. press any of the 6 extra buttons/paddles
3. none will light up blue as a detected input
