No more metathumbs since last upgrade

Hello, 

Since the last update I have a strange problem. I have movies in folders and in each folder is the movie, and two files, one folder cover art as jpg and another as metathumb and WD metathumb always had the cover art either.

Now with the last upgrade no metathumb ever, but the folder jpg yes, thats a problem for me cos I have so many folders and folders jpg are not good but metathumbs yes

I do not understand because they have changed the system

Example in previus FW  300…mkv

                                                   …folder.jpg

                                                   …300. metathumb (this was show like a cover art)

Example in last FW     300…mkv

                                                    …folder.jpg (now this is show like a cover art)

                                                    …300. metathumb

???

Hi, have you tried rolling back to the older firmware to verify if the problem continues?
