MPAA rating – remove rating description

I have been using Ember Media Manager for managing my movie collection, I can see while scraping Emby is adding mpaa rating description which is not being recognised by many parental control add-ins,
Is there anyway to remove the mpaa rating description while scraping with Emby.

Current scrapting
