Duplicated banner in Sponsors box

I am running ZenCart V1.3.8a. and am a zen newebie.
I have banners on the Right hand side of the site in the BannersAll group. Recently I moved a banner from the right, to the left hand side, using SideBox-banner group. For some reason the new banner suddenly appears twice, once under sponsors (not wanted), and once at the bottom under the menu (I want this one). I have managed to remove the sponsors heading, but cant remove the banner image.
The banner is in both BannersAll and SideBox-banners groups, but is disactivated in BannersAll. I tried deleting it from BannersAll but then it doesn't show anywhere:wacko:
What should I do to remove the banner that appears in the sponsors bit?

Thanks

Found it! I'd also got bannerbox2 turned on. I turned off bannerbox and that solved it.
Yay!:clap:
Thanks to everyone who looked at the thread.
