Printing with the raster box ticked

Hi - I've been battling with this problem for many years.  If I put shading on a drawing with transparity I have to tick the rasterize box on the print menu.  Sometimes though, when I do this, elements that I have deleted show up - a bit like a ghosting.  On the image below, the sofa has been deleted but it shows up on a raster print. Help appreciated, using Powerdraft V8i. It doesn't show up if I untick the rasterize box but then my shading comes out black.
