Hybrid Discs - CDs. Problem.

It appears that if someone tries to order a Hybrid release that the shipping program doesn't pick it up as there is no variation for Hybrids. Am I the only one to notice this or has anybody else had problems and has anyone notified Discogs so they can add an extra variant to the shipping program?
Apologies if someone has already started a thread on this but I didn't spot one.

Okay. Forget it. I think I sorted it. Whoever entered the original there was no weight for it so it was not connecting to a shipping price.
