Volume Up (Siri Remote) jumps in increments of two.

Using BTT 3.821, I've noticed something "new" in the last couple of days, which is likely since an Alpha update, but, I could be wrong.

The symptom is that I've bound the + and - buttons on a Siri Remote (new style) to macOS volume up and down. This was working great until recently, when any press will increment or decrement the volume by TWO levels, rather than just one.

I can't see any obvious toggle somewhere that may control this, so, thought it would be worth reporting. Not sure if it's a bug or not, but it was unexpected and different behaviour than my historical use of BTT with the Siri remote.

Any idea on how to get things to only +- in single steps?
