Market/App update limbo?

[FunN4Lo]

I have 6 apps that have been stuck in an update limbo for several days: Astro, Color Note, Google Sky Map, Movies, My Tracks, and Pandora. I have the notification that updates are available. Pull down the notification, click on the app to update, but the only choices I get are "Open" or "Uninstall". Other apps have appeared needing updates during this time frame and they have the "Update" or "Uninstall" options.

Any help for a fix?
