Unlink items from monday docs

How do I disconnect items created from a work doc monday doc?

The work doc items are now linked to a board on monday, but I do not seem to be able to remove them.

I tried to:

  • edit the item in the doc, but it removes the whole line
  • delete the item on the board, link remains
  • looking at the item does not appear to show that it is linked to a document

Any help would be great! Screenshot below:
