As you can see, I have an external reference in the route that I cannot seem to get rid of. I've opened the 3d sketch and filter for all external relation and in-context relation and there is none (I've removed all of them) and still the route is linked to something.
How can I get rid of this relation?
What is the difference between the route and the cable that is in the "Route Parts" folder? The cable does not show any relation and the assembly top level does not show any relation also.
