Let me preface this by saying that I have used this setup for years with no problem, so I am not exactly sure what I have done wrong.
I run a Plex server on my Macbook Pro which accesses all its data from my 3tb Time Capsule (named "FRIDGE") . My Movie and TV folders are located in the same folder on the TC (FRIDGE/Data/)
I had an issue, so needed to re-import my media. The movies are fine, displaying all the artwork and descriptions and playing just fine. However the TV shows are showing no artwork, titles or descriptions. These used to work fine. They are in the correct file/folder format.
One thing I noticed is that when selecting the folder to add 
it no longer has the name of the TC like it used to, instead will only show the "Data" folder.
However, as the movies seem to be loading fine I am not sure of what has happened.
I did a hard reset of my Time Capsule and used Appcleaner to completely wipe PMS from my Macbook in an attempt to start fresh, however the problem persists. The TV files are able to be played some times, although other times I get the "M3U8" error, which again only happens with the TV and not the music.
Any ideas? Happy to help with relevent logs, although this is a little steep for me so could use some baby steps instructions on how to assist.
Thanks, Shane
