I try closing down the application and opening it up again but the problem still remains. I was even dumb enough to restart my PC to discover that it still didn’t solve the problem.
But I finally found a workaround. All I had to do is refresh the datasource.
So if you are facing a similar problem simply click on the ‘Datasource’ tab located in the right panel. At the bottom of the panel find and click the ‘Refresh Datasource’ link button, and bob’s your uncle.
Usually just clicking the tab will automatically refresh the datasource and therefore display all your lists.
