Something started happening in the last week that I've not seen before. I'll have notifications on my "Marketplace" tile telling me I have update(s) but when I tap it and go to the marketplace screen, there are no updates showing. The other day it said I had four, but when I get there I only had one I could actually select and install.

Anyone else seeing this? I'm wondering if it has to do with WP8 versions of apps. Only started in the last week or so.
