As the list name tells, you try to delete a list generated by the Deck app. These lists are read-only for now, hence cannot be deleted. If you don't want to show them, go to the Deck app settings and uncheck "Show boards in calendar/tasks".

What I wonder a bit, though, is how you managed to delete this list. The delete button is hidden for read-only lists such as the Deck generated one. Since your Deck app is quite old (1.1.2), it could be that this version doesn't correctly indicate the read-only status of the generated list. You could try to update Deck to the latest version (1.2.3 as of now).

Thanks, I'll do it.

The delete button is hidden for read-only lists

But I fount it :) in console, this div element has style visible:hidden, I changed it and push the button. Thought, this is somehow connected with my list.

Hm, this explains how you could trigger this error. There sometimes is a reason why certain things are not visible ;)
