How to use Absolute order correct

Hi,

I have a TV show named

Quote:name - S01E01 - title.mp4

Season one is found correctly. The problem is the other seasons:

Quote:name - S02E20 - title.mp4

(first episode of season 2, 20th episode of the series). I have tried the absolute order for this folder, but the problem still exists.

Is there a easy fix or do I have to rename them all?

Videos are stored on Ubuntu 16.04 Server, so I could use "rename", but I don't know a good expression and all episodes are split in 3 parts.
