It seems that the checks for wether the banners are on or off isn't working when you set the Multiple Banner Groups in the Header Positions under Admin > Layout Settings > Banner Display Groups - Header Position 1.

My current entry is CPC:Wide-Banners for Header Position 1, which is allowing the banners that are off to display.

I have all Wide Banners off, except for 2, and I am getting banners that are supposed to be inactive coming up.

But they don't appear in the footer position 3.

I have not done extensive testing.
