I've had issues with the business policies for ages - namely that Ebay generates random copies of a particular policy and allocates a couple of listings into it. 

I did just go and have a look at the policies now that I saw your post and noticed that Ebay has generated a policy called "Ebay Managed Payments 377783223g000". It contains 11 of my listings. No idea when that was generated, or why. Or even why those 11 particular listings but I did notice that it is a copy of my "Buy It Now" policy.
