Exclusive Campaigns Not Functioning Options

[bsorenson]

I currently have an exclusive campaign dayparted to run over the noon hour consisting of 3 banners (a leaderboard, medium rectangle and a skyscraper) running in the same configuration on two sites. I've run this configuration previously on other sites with minimal issues but this one running on two websites concurrently is only pulling in the leaderboard which is the top-most zone on the sites. I originally tried having the three banners together in one campaign but that wasn't working so I broke them out so each banner was alone in its own campaign which worked previously. I'm half-way through the length of this contract and running out of ideas. The campaigns are all set to exclusive with stop and start dates. I've set the priority to 10, tried using the companion checkbox, nothing seems to work this time. We are using OpenX 2.8 hosted on our own server. There are multiple other ads running in each zone which should be essentially overruled by the exclusive campaign.

What am I missing on this one?

What am I missing on this one?

You're sure that maintenance is running fine and the zone probability page shows these exclusive banners in the list?
Are you using single page call?

I haven't had any maintenance issues with this server and the probability page shows the ads in their respective zone under the "Exclusive Contract Advertisements" heading. I've also switched to linking the zones at the contract level and still am only getting the leaderboard (the top-most ad) to show exclusively.

I am unsure of how to distinguish which type of page call I am using. Where would I find that info?
