Item Frames changing their visible position

The bug that I am having is very annoying to work around, as the position I place an item frame, and where they are visible are not the same, I have tried dropping an attachment below, but the video is too large, at 15MB, and it was not even 30 seconds long, so I have uploaded the video made to YouTube on my account and it is set to private, so only you and me can watch the video, here is the link. https://www.youtube.com/watch?v=ZuVPL39PH1w&feature=youtu.be

I am attempting a Diversity 2 1.14 remake, and so far all my problems have been to do with item frames, I would highly respect it if you could fix this item frame problem, as I no longer know where any of them are meant to be.

Thank you for reading.
