Good day Lewis,

I've just tested it (IJ-version 1.52t) and realized that the selected area
is in fact an overlay. When saving images with overlays in JPG- or
PNG-format, they are flattened, i.e. the overlay is imprinted onto the
image. This behavior isn't a bug.

What you can do, if you don't like the red square being imprinted, is go to
"Image >> Overlay >> Remove Overlay".

Regards

Herbie
