I've forwarded your Email contact to one of our Allegro PCB Editor Support AE experts. He'll be contacting you regarding this. Perhaps you may not have any vias punched in the design or none that apply to a layer pairing. I think it only addresses Blind and Buried vias that are in a layer stack.
This is getting a bit more in depth than my Allegro PCB Editor knowledge (my expertise is the front-end SPB products).
May I ask that you file a new Service Request via Cadence Online Support - http://support.cadence.com/.
I'm able to access that option in the viewer but not the editor (16.2). I can open a board in the viewer and i'm able to toggle that switch but when I open the same board in the editor that button is greyed out. The viewer shows the via label but the editor does not.
To turn on the via stack information, go to Setup> Design Parameters> Display and turn on "Via Labels".
how do you turn on the via stack information on the vias? ex.. 1-2, 3-6, etc...
