I have the following problem with NCIS.
For some reason Plex has decided to create random NCIS icons on the TV show Tab for NCIS. I have Season 1 to 12 are OK.
Season 13 is problematic.
It has episodes 1- 15 in the correct folder on Plex.
Episode 16 has its own Icon in Plex
Episodes 17 & 18 Have own Icon in Plex
Episodes 19 & 20 Have own Icon in Plex
Episodes 21 & 22 Have own Icon in Plex
Each season and episode follows the following protocol
\NCIS\Season NN\SSSEEE Episode.Extension
eg
\NCIS\Season 13\S13E01 Stop the Bleeding.mkv
This is the same for every season and episode. As below
