Odd behavior of Duct Terminal Arrows in linked file

[patricks]

I have a Revit building file with our mechanical consultant's MEP file linked in.

They use mechanical equipment and other families with little arrows indicating air flow out of the equipment. If I open one of these families, the arrow appears to be a Generic Annotation nested into the equipment family.

So then if I try to uncheck the Show Annotations for that linked file, the arrows still show up. If I turn annotations back on for the linked file, and then turn off Generic Annotations individually for the linked file, the arrows go away.

Why do they not turn off then I uncheck the Show Annotations option?

I suspect perhaps because it it nested into the equipment family, and the V/G control
for Linked Revit models can't "dig down" thru the equipment category.
