Dialog, Slide In and Interstitial Ads and they are not working correctly. They are loading into a different ad unit designed for 300 x 250 and now how it looks in the demos. How do I change the settings to make it work like the demo?
Ads that aren't targeted to a particular Zone or Placement can show in any Zones or Placements. On the demo, we created a "Utility" Zone and put it into the HTML outside of the page elements. We then target out of page (popup) style ads to the utility Zone.
Instead of naming the Zone "Utility", you could name it "Popups" (or similar) and set the Max Ad Count field to 1. This way it's more obvious what it is for and, by using the Max Ad Count field, you've restricted it to only show a single popup style ad on the page.
