Need assistance-Handless Extrusions in Cabmaker32 don't show up in Cutmaster, @gkernan can you help?

The handless C channels I select in Cabmaker Pro do not show up in Cutmaster.
They represent perfectly in Cabmaker but are just not there in Cutmaster.
If I include J channels, then the C and J channels show up in Cutmaster. However, I don’t require J channels on this project.
@gkernan why does this happen?
