Strange behaviors on save templates

I'm trying to get calibre to save books into a subfolder on a kobo device for better organization. Since the default is saving everything into the root folder, I have modified the save template to "/documents/{author_sort}/{title} - {authors}". However, this seems to have some very weird side effects, where some books will be saved to the "documents" folder, but others seems to be going to a folder called "docuents" instead.

Edit: "/documents/{title} - {authors}" seems to work fine even with previously problematic books.


My apologies if this is a dumb question and I'm missing something obvious, but does anyone know why my save template is causing this strange behavior, and how I can fix this?
