I know there is a total confusion with air dates and episode numbers in every season but there is no confirmation needed from anywhere to see that it has no sense at all that after 4X36 comes 4X104-4X139. 4X104-4X139 is definitely non-existent, so should be removed. Thank you!
Waiting for TVDB to fix it.

We use TVDB for all data and it looks pretty messed up over there. Notice in all seasons (but season 1) the numbering is all incorrect and there is no episode 1, etc. This will need to be fixed on TVDB first, then I can update Trakt to match.
