Dashed lines not displaying

[BeDazzle]

This is new and odd. When I create a dashed line it shows correctly.

As this is part of a packaging dieline the strokes need to overprint the artwork.

When I switch to Overprint Preview the stokes view as solid, and when I switch back they remain solid, but still show as dashed in the Stroke panel.

Only when I view the Separations of just that spot color does it show as dashed again.

Using Illustrator 29.6.1

Can you show the appearance panel for that path?

Here you go.

What is the appearance applied to the layer?

Well done Doug.

I have been using Illustrator since 88 and never noticed the Layer option in the apperance.

It had an overprinting stroke applied.

Thanks so much.
