Group objects are not visible

My best guess is a browser issue. I experience this from time to time and just switch browsers to mitigate. I use Safari and Chrome.

There is also an issue if you click yes to the "yellow" https message that pop up sometimes when you log in. You then need to go into Configurator -> Utilities -> System and make sure that both http and https is enabled in the menu Services -> Http server.

Hope this solves it for you and that it's not a wider hardware issue.
