Cannot remove list from board

Hello, I hope this is the right place for this question.

I’m trying to remove a list from the issue board. I can only see an “Add list” button, which I can press to add new lists from tags. However, when I deselect a tag (instead of selecting it), the list doesn’t disappear from the board.

How can I remove the lists I don’t want? Thanks in advance.

I’ve opened an issue about this (https://gitlab.com/gitlab-com/support-forum/issues/4327), it’s probably a bug as it was working before…
