Is it a known issue that episodes watched from a widget do not show up as watched after they are done? Shows watched from the library itself do...just not from widgets.
Edit - Sorry I was mistaken, no shows streamed from an addon are showing up as watched in the library, either direct from the library or from a widget.

Maybe you should use the Kodi library to watch content instead of (banned) addons ?
For issues with addons, you should contact the addon author. The only thing you can try is setting the "force widget refresh" option in the shortcuts settings.

Try resetting the function cache in the URL resolver settings that should do the trick.
