**Describe The Problem:**
After changing Unifi Chime volume to any level >0%, it jumps to 100%. Changing to 0% works; non-zero settings jump to 100%.

**To Reproduce:**
Pick a Chime and set the volume to any non-zero level using the slider. The volume will briefly show the level you set it to, then jump to 100%.  Setting to 0%, however, works properly. Very rarely, the volume change does remain at the level I selected.

**Logs:**
I don't see any log messages when setting the volume.

**Homebridge Configuration:**
Let me know if you need to see anything, but since there are no feature options for chimes (other than to disable them), I didn't think the configuration is relevant.

My doorbell and chimes are on a UCKgen2+; there are no other cameras on that Protect controller.

**Screenshots:**
Let me know if you would like to see a video of the behavior.
