I have no idea what you are doing and why you are doing it when nobody told you to do it :-P
Where are you located?
All your epg is set to Chicago time, which means UTC-6
What does it mean offset for you? to what is it 6 hours off?
What is 6 hours off exactly?
What channel?
You need to understand what timezones are and how they work.
Also changing the timeshift in the m3u editor does exactly nothing for you and has nothing to do with timezones.
And maybe you should look at that plex and xteve crap, maybe they have also timezone settings which make your epg off by 6 hours.
If they run on a server, then even the server has a timezone.
If you reinstalled everything from scratch, then they are probably in the standard setting which is most probably UTC
