I'm trying to follow this guide
https://manual.calibre-ebook.com/sub_groups.html
and have successfully set up a hierarchical column #folder and entered the template
Code:
{#folder:subitems(0,1)||/}{title} - {authors}
in Preferences -> Saving books to disk
When I save to disk I get folders that look like spelling errors that I swear are not in my custom column
Code:
$ ls
_catalog ficion fiction fion fn nonfiction
I have entries in my #folder column that go three deep such as "fiction.sff.shortstories" but none like "ficion". The tag browser works as expected and shows none of the odd tags.
All of the wrong folders have some books, but I can't yet see anything special or odd about these books or their metadata.
I attempted to write a template to Save to Disk in a 3 deep folder structure, which has similar errors.
