When I draw a box in Omnigraffle the line is greyed out

When I draw a box in Omnigraffle the line is greyed out? Do I have some setting that is forcing this or is this a bug?

You don’t show it here, so just to cover all bases: What color is the Stroke set to?

Thanks. My Stroke Inspector was floating and hidden. I never float them so it wasn’t something I suspected.
