Black bars show as previously watching content

Hey guys I got a question. Using the new Nvidia Shield, when watching older TV shows/movies that are 4:3 ratio and have black bars on the sides of the screen, I see the previously played 16:9 ratio content where the black bars should be.

You can see an example here:

This is on the Nvidia Shield 2017, using the Play Store Kodi with beta opt in to the v17.
