View bounding box, component/top level envelope setting won't clear

Hey all, 

Has anyone had an issue with these 3 check boxes always re-setting in the heads up view toolbar? In both parts and assemblies?  i've checked settings, updated templates, but these keep re-setting to be shown.

I'm using SW 2020 SP0.0 (can't install newer version).

Its causing interesting graphics issues, and turning these off fixes it - but they won't stay turned off!!! 

appreciate any help on this one as it's driving me crazy!!

Cheers
Duncan
