Addon updates all ratings correctly…but few shows after kodi restart would revert back to tmdb rating instead of the imdb rating used by this addon. Not surr why. Happens always without fail for few shows

I don't see how that can happen. Have you set IMDB as the default rating in the settings for this addon?
Are you using local SQL or MySQL/MariaDB setup?
How did you initially add these tv shows to your library- scraper or nfo files?

Can you provide enable logging in the addon settings, then run your ratings update, and provide the LightIMDB log which is located in addon_data folder in your Userdata (wiki) folder.

heres a quick log, yellowstone is one of the shows constantly changing on its own

Hello @Lomar2, sorry for my late reply.

The behaviour you descrbed is indeed quite strange and I don't think it can be realted to the add-on. If the rates are reverting back to the TMDB ones, there should be something else changing them...may be you can provde more information about your DB setup as requested by @Karellen so that we can try to understand what is going on...even if it doesn't seem so trivial! 

Cheers!
