you can navigate to the series entry for the show you want to align at kodi and use the context button, there is a information selection where you can refreshes everything from disk
It looks like texturecache.py was used for that purpose, some users tested it for Nexus so probably it works for Omega too.
texturecache.py qax movies @qaperiod=9999 @qa.nfo.refresh=1
where "@qa.nfo.refresh=1" means: refresh (remove/reload) all movies with nfo file modified during previous 1 day.The problem is that it needs Python 2.x which is not available with Omega, so probably the easiest workaround is to bundle it together with old Python into Docker image and run it that way on LE.
Isn't that an item by item approach?
its the same for a whole show, I just hadn't one for an example 
so you update a whole show it updates everything regardless if 1 or 1000 files
Remove the show from library, but don't delete files - select "Yes", then "No" when you select "Manage" > "Remove from Library".
Then update library.
If it doesn't reappear go to Videos > Files > TV Shows and select the TV show then select "Scan to Library"
