Missing purchased movies

I have 88 movies that show up under 'purchases' on my X1 box. When I look at my account online, such as if I wanted to log on and watch a movie through my web browser (not through an app), there's only three movies that show up. When I look on Movies Anywhere, only one movie shows. Any suggestions as to how I can sync everything with my DVR box so all the purchases will show? I understand some movies won't show on Movies anywhere, but only 1 out of 88?
