Wrong show every time – how do I stop it?

Any time I add TV episodes from certain shows it always adds them as a different show.
Eg: Shooter is always added as goong s (which I’d never even heard of)
I am using a centralised mariadb to store the information. I’ve tried to remove goong s as an option but may not have done so correctly.
If I tell Kodi to update the episodes data from the internet it corrects it to shooter.
My structure is:
Series->S->Shooter->Season 01
I’m using Kodi 17 rc 3 but this has always occurred.

Any help would be hugely appreciated.
