I have two paths - one traced bitmap, another created from rectangle. I want to separate lower part of the traced image by using the rectangle path. However Path Division removes the whole image. Could you please advise what is wrong? Link to SVG.

Select all the pieces of the top part only, and do Path > Combine.
Repeat step 2 for the lower part.
