Steps to reproduce the bug

1. In Davx5, set up an account to synchronise some Calendar (from Nextcloud).
2. In Fossify Calendar, refresh to get the new calendar.
3. In Parameters, choose Manage calendars.
4. Change the title and the colour of the synced calendar.

Expected behavior

The calendar should appear with the chosen name and colour.

Actual behavior

The calendar name reflects the chosen title, but resets after a while.

Screenshots/Screen recordings

No response

Additional information

There is a setting in Davx5, under CalDAV, to state that the colour of the calendar should be set in the calendar app options, and this does work. However, there is no such setting for the title of the calendar.

The question is bugging me because I get calendars from several organisation that I am a member of, and within their respective Nextcloud instance, they are given a title that makes sense in their respective context, but not in mine. For example, OrgA and OrgB will have a Bureau or Comité calendar, and I need them to appear as OrgA and OrgB respectively, not as Bureau.

I'm not renaming them, but my WebDAV calendars keep losing the colours I set on them. which I wouldn't mind too much if they weren't all a very similar shade of cyan/teal.
I've done a settings export after setting the colours, and then tried to apply the colours afterwards, and it that didn't apply the colours back. Is the colour being set on the calendar itself? (idk if calendars themselves have colour as a field you can modify on them)
It doesn't seem like it is being persisted anywhere other than in app memory.
