Thank you for your help. But still having problems on MovieSets.

Kodi 19 is the first version that supports movieset images out-of-the box. The current version of Ember does not support these new folder/file name structure as default option, you have to set it manually in the file name expert settings (folder and file name) and in Kodi (folder). Check this post for more information: Link

Ember needs a folder to store all movieset images, if you use custom expert settings or the current default file names for the Kodi Interface. The Kodi Interface can sync ANY file name/path to Kodi, so if you set the new folder/file name structure for Kodi 19 you don't have to enable also the "Kodi Interface" default settings.

NFO for moviesets are not needed because all information will be stored in the movie NFO if you've enabled the option Settings => Movie => Scraper-Data => Collection => something like "extended movieset informations in NFO".
