Can't update WPMU DEV Dashboard

Hi. We have Appointments + installed. But we got an Update notice for WPMU DEV Dashboard. I can't figure out how to update this. If you look at this screen shot, , you will see that there is no checkbox beside it to update the Plugin AND you will also notice that WPMU DEV Dashboard does not appear in the left navigation of the WordPress Control Panel. Further down the page (as shown in the screenshot at, you will see it says there is a new version. When I click Installation and Use Instructions, it talks about installing. I am fearful of installing it fresh and losing all our configuration. FYI, if you look at our Installed Plugins list (screen:, it show it is Activated. So how do I do an UPDATE?
