Yeah, I've been getting that. It shows current version instead of the updated one.I'm having the issue of new updates first appearing as "open."
When I first open App Store any programs that want to update will appear in the list, but will have the word "open" next to them, as if I had already completed the process, or simply showing the current version without the option to initiate the individual updates.
I need to quit the App Store and reopen it to "wake-up" the update process and present the individual "update" buttons.
It's happened for a few days/a few times already.
