I cannot figure out this crop problem I am having.

Hi,

I am new on this forum so please let me know if I am posting this in the wrong category.

I have a problem with CDx7 not cropping my photo properly. What I am doing is creating a catalog for my small business and I have a master layer for all pages which is basically a grey background. I am using this grey background a guideline to all the photos I am going to be placing in the catalog. So as you can see in the video below, when I try to crop the photo according to the master layer, it doesn't only crop the right side, it also trims from the top. What am I doing wrong here? This method worked perfect for 20 something pages but now it doesn't.
