We had to place the photoshop file with the spot channels (seps) included into illustrator - this is our working sep file before we delete the RGB channels and save as .dcs. That worked for us.
Another less desirable option would be go really old school and split channels and place/relink the individual tiffs overprinting into illustrator for output.
Really needs to be fixed!!
