Hi all!
In my Task-workflow in a simple Jira-project, I used to have a status 'Klaar' ('Done' in English'). Yesterday, I deleted this status from the workflow, and added the status 'Gesloten' ('Closed') instead.
But now, the column for 'Klaar' is still there in the project board (business project). I don't know why.

I only use 1 issue type in this project, so only 1 workflow and that doesn't contain 'Klaar' anymore. It's not possible to drag and drop a card in it, the card bounces back.
I still use Klaar in other projects. In the admin settings > Issues > Statuses, it confirms that Klaar is only used in other projects. As expected.
The workflow:

How can I get rid of the 'Klaar'-column in this board?
Thank you!
