Adobe Acrobat is printing the bounding box on my images

Hi there. I have a pdf saved from illustrator. I open in Acrobrat for print and it always adds a bounding box on transparent background images. The image file type in illustrator is psd and it has no background. How do I keep Acrobat from printing the bounding box? I have never had this issue until last November. help me out y'all. 

Thanks
