TVDB Not scraping multi part episodes in DVD order

Kodi Version : 16.1

I have a TV series that has two episodes per file. thetvdb.com DVD ordering page shows these correctly as 1.1,1.2,2.1,2.2,etc (http://thetvdb.com/index.php?tab=season&...&order=dvd)

I have named my files like the following

s01e01.1.s01e01.2.mp4

Which is what the naming videos/files Kodi manual says is the correct way

But when I scrape the series, I only get the first episode of each multi episode, not the second

My debug log can be found here http://pastebin.com/diAGpb5t

I believe the important lines are here though

09:16:39 T:3304 DEBUG: VideoInfoScanner: Scanning dir 'nfs://192.168.2.5/media/Kids TV/PJ Masks/' as not in the database

Anyone got any clues?
