Update 9.4.3 issues with app store

So I have updated to the new 9.4.3 iPhoto 4 times since it's release, and every day the app store tells me that I need to update iPhoto 9.4.3 to iPhoto 9.4.3. Is there a reason why app store keeps telling me I have new update available even though I have already installed the update many times?

Thanks.
