Raster transparency ignored when printed

This pertains to migration from v8i to Connect. I've been running Connect for a week now and dealing with miscellaneous things.

Most of my projects use raster images attached to the master model, referenced in a sheet and transparency modified in the sheet. Most of them work fine, but I have one file that doesn't work. When printed, it ignores the transparency I've set for the raster image and just prints it 100%.
