Can't change calendar color

Greetings, I am om eMclient 9.1.2109 on Windows 11. I have two gmail accounts on my client and two imap email accounts. The calendar view shows me my google calendars no problem. I also added a caldav account for one of my imap accounts. The caldav account is hosted at bluehost.com. No problems at all using any of the calendars. I can change the colors of the google calendars no problem. There is one local calendar, which I don’t use, but I can also change its color no problem.

But when I try to change the color of the caldav calendar, the color changes, there refresh spinner on the account flashes for a few seconds, then the color reverts to what it was originally.

Anyone else seen this problem? Is there a workaround? Is there somplace to reports bugs. I’ve only been using eMclient for about 24 hours so I don’t know if there is a more official way to report bugs.
