Android - TV shows are not showing up in the TV Shows page.

New to the forum and my first post. 
I recently purchased a Firestick and installed Kodi. I have my media files (movies and TV shows) stored on a USB drive attached to a DD-WRT router and accessed by smb://LZDCD1/Movies/ and smb://LZDCD1/TV Shows/. The movies and TV shows are mainly stored as ISO files but there are some .mpg files. I have successfully set up the Movies in the library and can play them from the main Movies page. I am having trouble with the TV shows. I have read the wiki for the folder format and naming conventions for the TVDB. I was initially able to get a couple of TV shows to show up on the TV page and play them but when I updated the library they disappeared.

From the File Manager I can see all of the TV show files.
From the Media settings/Library/Videos/Movies I can see all of the movies.
From the Media settings/Library/Videos/TV shows all I see is ..  No files are listed.
Displaying TV Shows at the main screen, but not selecting it I can see the fanart for Poldark and Victoria but when I select TV shows the list is just ..

I turned the debug logging on and restarted Kodi
I went back to the Media settings/Library/Videos/TV shows and changed the content to none and back to TVDB and refreshed.

The TV shows remained empty.

The log file has been uploaded to http://ix.io/Q2p

Is there any other information that I need to add?

Any help with what I'm doing wrong would be much appreciated.
Thanks in advance,
Ian
