file format gets added to title preventing correct scraping

Hi guys, I'm not very technically gifted so i don't understand why a plain movie title on my nas shows up with the .mkv or mp4 added to it when the Ht5 tries and fails to scrape, it doesn't happen to all but still a pain. Is there a way to ignore the file type when scraping

 

More detail needed - not really sure what you're saying is happening...
