Library title problem.

Hi (I'm a newbie)

I have a standard installation of Kodi 17.6 on a Raspberry Pi3 (Stretch) with Pixel desktop. (Don't know for sure, if that's what it's called)

I have some chinese movies, (on a FTP server) that are shown/named with chinese characters in the movie library. 
If I go into 'info' and press 'refresh' I can choose the correct english title, but when Kodi updates, it still chooses the chinese version.
Example. The movie CJ 7 is named 長江七號

I have tried to remove and rebuild the library a couple of times, and changed naming settings in the scrapers. But nothing have helped.

Any hints?

Thank you
