On the flatten Route, why do some cables not show?

I have a flatten route that doesn't show a coax cable. It will move the connector as well as all the other connectors in the harness. It wil flatten all of the wires, but will not show the coax one. When I edit flattened route, it shows the lines for the cable, I can drag the lines anywhere, but when I save it the coax line doesn't show. Anyone else having this issue?SolidworksRouting
