Red Box covering content of a .pdf when "Placing" onto a page
Hi everyone, I'm wondering if someone might be able to explain why this is happening to my pdf's that I'm placing into an InDesign file.



As you can see, in the PDF I am importing, there are two red rectangles covering pictures of uniform colours when I place that file into my document. It is not there in the actual file itself, so I'm sure it's just a setting I am missing.
Any tips on how to resolve this would be appreciated. Thanks
