Episode Sorting – Mac and Windows

Just upgraded to Kodi 17 – Both on Mac OS X El Capitan and Windows 10 (2 Separate Machines)

Using the Favourites feature I have created a link to “In progress TV shows”

From here I have sorted the shows by episode.

Prior to Kodi 17, when this was done, the result would sort the episodes by the remaining un-watched episodes. Now when doing this, sorting by episodes now sorts by Total episodes.

I have replicated this on both the Windows Machine and also the Mac, swapping out different themes does not change how this is now presented.

Is this a intended feature or an oversight?

Any suggestions are welcome.
