Photos not cropped when exported from Writer (for Mac) to .pdf

I’m using LibreOffice Writer for my MacBook and a brochure I have created looks GREAT! However, when I export it as a .pdf file, the images are the correct size, but no longer cropped (as in, it is the uncropped photo filling up the same space in the .pdf as the cropped photo in the .odt).
Is there a workaround? I need to get this printing job done ASAP!
