It also isn't obvious why you want the series twice in the path

IMO a template of this complexity should be written in Template Program Mode (TPM). Not only is branching easier, TPM templates are much easier to debug.

The problem if I do {title} outside of the template expression is that I would then have the title of the book in the filename twice if it's not in a series. The intent is to match up with a program I used called Kavita and their intended library structure of:
Library Root
┖── Series Name
┖── Series Name.epub

I'll look into the TPM template.
