Strange Flickering between two images

Flashing colors warning

I don't really know how to describe what this error is, but hopefully the video will clarify:

Imported my psb file to AE and dragged a few of the photoshop sequences out of the folder that came with it. Then, to expand how long they stayed in the shot, I used the Interpret Footage feature to increase the number of loops. When I hit play, for some reason it flickers between the black and white farm scene and the color hill and wheat shot. The problem is that those files aren't even in this composition and were never being worked on with this particular project. I don't know how AE drew them in or even where they came from, but I'm not trying to use them.

Imported composition and retained their layers > Interpreted footage and increased loops

I expand on this in the second tab to show that it swaps with each frame.

Please help get rid of the color frames
