SAVED MOVIES NOT APPEARING IN APP

Have had this problem for awhile, well over a year, but I didn't address it sooner because I rarely use the app.  The problem is that the movies I have saved as favorites in 'My List' do not show up in the app, only via the cable box, and this started before the app was even a thing.  The television shows I have saved as favorites in 'My List' do appear in the app, but the movies do not.  I've tried marking movies as a favorite via the app but they do not appear in the app either.
