In an assembly, mating a feature to a primary plane (a best practice), when selecting a face of a part, then I like to hover over the primary plane on the in-model-window tree that appears during mating such that the plane appears in orange highlight.   On one machine I use, this happens as desired (see image below).  I use 2 machines with SW2016, and each behave differently - on another machine, the planes do not appear while hovering.  Does anyone know where this setting is? 

Note that I prefer to keep the primary planes not visible in general, only want to see them at hover during mating.  Thanks in advance for the help.
