Google AdSense ads and FeedBurner - Not Playing Well Together

I am using the new version of Google AdSense (no link for me to revert to the old version) and I am unable to remove an ad from a FeedBurner feed that I have. There is no “Disable” or “Remove” link for the ad and it is always marked “Active”.

Any ideas on getting rid of the ad from my FeedBurner feed without having to nuke the feed itself?

Have you tried deleting the feed in feedburner then recreating it?
