We use Nextcloud Deck. Unfortunately, we have a bug: It happens with certain cards in certain boards that a tag cannot be deleted. Clicking on the x simply does nothing.
If you open the dropdown and add another tag, you can then also delete that one and the other. But as soon as you click into another board and back again, the deleted tag is there again.
I have also noticed that the tag is “frozen”, so if I rename the tag in the board settings, this renaming does not take effect. But only in the cards where it cannot be deleted.
The behavior is consistent once it has occurred. Unfortunately, I have not yet found out how to reproduce such a “broken card”.
It occurs in a board with just 2 lists, but 27 tags.
My hope is that it is a similar known problem and a solution already exists.
My only workaround is to manually recreate the card, but that is very impractical and time consuming.
Thank you already!
This is my first post, I hope I’ve been good so far
