Movie scraping issue

Hi

I am using Kodi v17 and Universal movie scraper on a Win10 x64, and also Nvidia Shield.
I have a large collection already that the scraper has detected with no issues, except one movie:
Piranha 3D (2010) by Alexandre Aja is for some reason not being scraped correctly. It has been detected as a movie called Piranhas (2010) and is a comedy and IMDB does not know that movie at all (well I will agree that the movie is comical but it seems IMDB has set Piranha 3D in the horror genre). No movie poster is detected. Movie plays fine.

File structure:
\\NAS-media\SD\Movies\Piranha 3d (2010)\Piranha_3D.mkv

How can i get the movie scraper to do its job correctly.
I have tried to clean the library but nothing seems to work.

Any help that leads to correct movie scraping will be appreciated.
