The '?' after the '-' look a little bit suspicious to me and may be responsible. If your books file names are all in the format

Book Series - 01 - Book Title - Book Author.epub

try this:

Code:

(?P<series>[^_-]+) -\s*(?P<series_index>[0-9]+) -\s*(?P<title>[^_-]+) -\s*(?P<author>[^_].+) ?

This will only work for the above mentioned pattern. If you have books without series or with series but without series number or any other combination it will not work.

As an interesting note, in my older calibre version (0.8.55), your original regex did extract the book title correctly in the test.
