TF Rubies, mortise doesn't show in shop drawings

I am working on a timber frame drawing and I have the TF Rubies extension for creating purlins. After I make the purlin a component and paste it in place, I make it into a joint. This usually automatically creates a mortise in the component that it connects to, but I have a few components where the mortise doesn’t show up in my shop drawings. I have tried erasing and redrawing the purlin, making sure I didn’t miss any steps in creating the joint, but it still won’t show up in my shop drawings.

Can you share the .skp file so we can see what you are working with?

The shop drawing is of the orange component. As you can see, the purlin of the green component isn’t showing up in the shop drawing even though it’s in the drawing itself.
