Circle "Mark as Watched" being reset every time

Hi,

I am streaming from a network drive (WD My Book Live 2Tb). There’s a circle that if full, means that I’ve already watched that episode. This is extremely helpful ! It’s working fine however, whenever I turn off then on my WD Live, it seems that all circle reset and are empty :frowning:

Any idea why and how I can fix this ?

Thanks 

Use the Media Library functionality.

It’s already turned ON. 

Still doesn’t solve it !

And is your content source actually set to use it?  (Red button)

Thanks for the reply !!
I think initially, my content source was set to Network Share.

I witched it to My Media Library !! This is great because I was able to add a folder to  my favorite to access it from the Dashboard. However, now once I got to my Dashboard, I go to my favorites, click on that folder, i get the following message: “The last content source has been removed. Please select a new content source”.

Any idea why ?

Thanks again for the help. !
