Grid Line bubbles not showing in Section Viewports

[Christiaan 982]

Any ideas why my Grid Line bubbles aren't showing in Section Viewports? Just the lines are showing.

Does the Grid Line style's geometry include a class that might be turned off in the viewports?

Thanks for prompt Andy, I did check that but not thoroughly enough. It was on None class but I use A-None instead and None regenerates every now and then.
