It is only affecting these particular images but it's doing it to five out of five of them. In fact, there is a full page width image right above them that is unaffected. Text frames are likewise OK.
Page size is US Letter. They print to my printer with no problem. The same pages exported to EPS looks perfect, just the way I would expect the PDF to look.
I'm actually not quite sure what kind of image it is. It's not even in an image frame. As I said, I highlight the cells I want in LibreOffice, Ctrl+P, click into Scribus to give it focus, Ctrl+V, it appears in the middle of the workspace, and I drag it into position and size it by dragging the handles. I get a nice crisp image with no fuzz like a raster, so I was assuming it's some kind of vector graphic. When one's highlighted, the only feature not greyed out in the Properties window is "Group", none of he image attributes are available.
I have a smaller (narrower) one in the same document (bottom of page 5) that isn't getting cropped.
