Same image to two versions of the same document but one shows white box from other image behind it
Hi, I am adding the same image to two versions of the same document and yet on one, there is a white box from another image (that was in the PDF when it was created) visible behind it. It also appears that the second image is lighter than the first. I am attaching a couple of screenshots for reference. The PDFs were generated through Vellum on different days, but the image being added is the same. I have tried copy and pasting the image that does NOT show the visible white box into the other document to no avail. What is causing this to happen?
Thanks in advance!
