Boundaries showing for non-display references?

Question

Is this expected behaviour? 
 When I turn on Boundary Display in some views I get 
 
 I have 30 or so references, all of which have display turned off. 
 What can I do to stop these from displaying?

The two taller ones with the solid corners look like Clip Volumes/Planes, but the others do look like typical reference attachment boundaries. But that is the purpose of the Boundary Display attribute - to display both clip volumes and reference boundaries.
