Hi thanks for the reply, they are all mp4 format. All internal metadata are wiped via this method and in the agents list, the ‘Local Media Assets’ is at the very bottom, also I have this unticked (have also tried it at bottom and ticked too).
The Plex Dance thing I had followed before and tried once more before this reply, still to no avail.
There is no where what so ever to suggest Plex should be naming this particular season as “Octonauts Series 2” and by doing so, making Plex put it as a whole new show altogether. I’ve removed all 4 seasons and tried adding them in alternative times, and the end result is always the same even though the entire file and name structure is identical.
I have even renamed the files in as many variations as I can possible think of by following everything said here. I’ve hit a brick wall now with this
