[CA] Axiom Marina symbols

I've got the Axiom 9 home for the winter running on the bench. 3.2.101

I've got a Navionics card installed with Freshest Data.

Marinas are displayed as, well, "sailboats". I want to remove them from the display. Their visibility seems to be tied to the display of "Navigation marks". That is, to remove the marinas, I need to remove all nav marks.

Is this correct? If so I'd call this a bug, or at least a very-strong feature request to be able to suppress marinas but keep ATONs.
