Movies count lower in Plex, but Kodi shows accurately.

Hi all,

I have been a long time Kodi user, and recently moved to Plex. Intially i had used Kodi's third party app "Media Companion" to scrape my movies.
And the movies count show up accurately in Kodi. But when i moved to Kodi, and added the movie folder to the Plex library, the movie count is close to 700 movies low.

Is there a Plex scraper (third party or inbuilt) that i can use to add the missing movies to the libary, but i would not like to mess up the original metadata that kodi downloaded in the first place. I'd just want to find and add the missing movies in Plex.
