The Libre uses the Jetbook driver I think, and the driver default is set to the following:

{author_sort}/{series}/{title}

So, again, there shouldn't be an issue, unless you've changed it. Have you double-checked the metadata for the file you're using, in Calibre? It's possible that you have the title set to "author - title", I suppose.

Renaming all your files is what Calibre is for, so figuring out how to do it will save you many hours in your future.

Maybe some more details of how you're processing a book, from HD to Calibre to Libre would help.
