Hello, I recently just noticed a error has occurred with some of the motion tracking I edited

Im not sure how to put this into words, but its the objects im editing are now disappearing into an invisible wall when earlier this was not the case

Here's are some images to help illustrate what im talking about.

as you can see in the images, the gift card I edited in is disappearing when its in certain angles. Im not exactly sure what I did to cause this but im a little afraid to find a fix for this since myself I put a few hours into this edit already and I dont want to lose my work
