I created a banner ad and assigned it a zone. I also have some sidebar ads that have also been assigned a different zone. But now when I place my banner ad on the top of my page it also creates a second image and places it in an unassigned zone.
I have gone back and checked all of my zones and they are correct (no conflicts) and made sure the correct zone assignment was checked in the actual ad and it was.
Can you please advise.
