Hole Glitch

I don't know how to title this but I have an .stl that gets distorted with random holes when applying a hole in a different area. Seems to be a glitch but perhaps I'm doing something wrong. The file has 4 pieces to 3D print, but it's just too much to do at once. I already did the 2 larger pieces, but now I need the smaller ones. So I create a large block hole to delete the large pieces, and it does. But it also makes some weird cuts/holes in the small pieces, which my hole block was not touching. I uploaded a video to demonstrate, link below.
