Unifi Chime changes ringtone when adjusting volume via Home Assistant

Hey guys!

I have two UP-Chimes for my doorbell. One doorbell has a configured automation from Home Assistant, which adjust the volume of the doorbell.

I‘ve configured the Traditional ringtone in Unifi Protect. Each time the Home Assistant automations runs, the volume is adjusted correctly but also the ringtone is set back to default.

is this a problem from Home Assistant oder Unifi?

thanks
