Thank you so much! This instantly fixed the issue for me!
It's a bit of weird one. The bars with custom bar value objects never exhibited that issue, but the bars using Preference values like the ones for the audio controls definitely did for me. So the ones provided in the expansion like "Left stick sensitivity" never had this problem cause they use custom classes inherited from BarValue. Making python classes inherited from BarValue was the workaround I have found to work. I tried that for the volume sliders, but it can be a bit funky sometimes and the value can sometimes jump around oddly.
Anyways, thanks again and thank you for the effort you put into this project!
