Apps not getting updated in iTunes?

I usually update apps in iTunes and then sync with the iphone. But today I noticed in iTunes when I click to update an app, it says this app has already been purchased and check available downloads.
Wondering if this has to do with app thinning and is anyone else noticing the same.

Also a separate question - is there any way to cancel download of apps which were purchased but canceled in the middle of download. I have hundreds of such apps which I do not want to download now because of limited bandwidth. Problem when I want to download an app, iTunes queues that app and starts download of all the apps. How do I clear that list?

 

just updating... could be helpful - I called Apple support and requested them clear the "Available for Downloads" list. After that, it's working now.
On forums many people suggest to delete list.plist file but that has nothing to do with this list. It's on the Apple server and they can clear it, users can't do that on the computer and iphone.

This could be helpful to other members looking to clear this list.
