How do I remove Joplin notes that no longer physically exist on the server?

Maybe one of you have experienced this as well. I had installed both NC Notes app as well as Joplin on a number of clients. The formats of these notes are dissimilar and do not match well, so I decided to move Joplin to its own folder. It turned out there were less than 100 Joplin notes in the users’ Notes folder, that weren’ t critical.
So I created an extra folder in the users’ Files root and proceeded to delete the Joplin notes on the server. But now those joplin notes still show in the users’ files web-interface. I can’ t seem to get rid of them in a browser, and get error messages.

Has anybody experienced this? Can anybody point me to how to remedy this?

Trying to manually delete them from the Notes app does not work.

In the logs, I came across the following:
