Deleted libraries are in Find Duplicates "Cross Library Search"
I noticed that in Find Duplicates "Cross Library Search Options" the dropdown list of libraries contains a few calibre libraries that I have deleted. I had created a few test libraries as a sandbox for learning calibre; they have been deleted using the "Remove Library" function and the folders have also been deleted.
Is there a relatively easy way to "prune deadwood" from the dropdown library list?
Hope you're having a good New Year ...
