Unable to rename Contact birthday calendar

[Valdnet]

Steps to reproduce

1. Create a Contact birthday calendar.
2. Change its name to something else.
3. Refresh the page.

After refreshing the page, the changed name of the Contact birthday calendar returns to the original name and the user's avatar disappears (not shared). The calendar menu also changes from Unshare from me to Delete.

• Before renaming:

• After renaming:

• After refreshing the page:

• The same happens without changing the name. After refreshing the page, the calendar is not shared with me.

Calendar app

Calendar app version: (see apps admin page, e.g. 2.0.1)

Server configuration

Nextcloud Version: (see admin page, e.g. 17.0.2)

This is still an issue, unfortunately, which would be great to have addressed. The inconsistency can bother some people between their calendars, especially if they use quick, short names [for their other calendars] like I do (eg. School, Work, Personal, etc.).

Maybe the issue would be better titled with Unable to rename Contact birthday calendar 🙂

Still having the issue

After some very light digging, it seems that the problem is on the server side, as I noticed no difference at all between the API calls and the results when trying to rename both normal calendars and the birthday calendar. Indeed, the problem is occuring after reloading the page, and the server is sending the older unchanged version. I didn't find much about the server on this repo, is this in the https://github.com/nextcloud/server repo ? (Sorry, really new to Nextcloud, I know this is a trivial question)

Issue is not fixed, still unable to change the name and color.

Indeed - the DB changes but the propfind for the user doesn't return the data that is there but a predefined string:
