[Closed] Strange Imported Objects from Rhino ?

Hi, I am working on a deselection tool, and the code I have got works for everything apart from these Objects imported from Rhino … It seems to remember its old selection for edges, so I can never seem to clear them properly. Like, even if I go into the subobject level and make sure there is no edges selected, I run my deselection code and the edges some how go back to its old selection. Does anyone have any idea why this would be happening ??

mm->ClearFFlags(MN_SEL);
	mm->ClearEFlags(MN_SEL);
	mm->ClearVFlags(MN_SEL);

This is what I’m using to deselect.
