Small bug in IOS7?

Dear all,

Not sure what this is all about, hopefully someone will have seen this before! I have upgrades both phones to IOS7, but they appear to behave a bit differently. When I download an app update on the iPhone 4, it will disappear from the update available list, however on the iPhone 5, the downloaded apps still appear, the apps downloaded work fine and the phone doesn't offer it for download again, but I now have a list of updated apps going back to late Sept. I am that there is a setting somewhere, I don't know where

Any ideas?

Thanks
