All campaigns that are active, and have a goal, appear as one of the options on the Campaign Progress dropdown menu on your dashboard. When creating a new campaign or re-activating an inactive one, be sure to hit Save, and then click on the Refresh button on your Dashboard to make the new campaigns appear. A Campaign will only appear on the Dashboard if it has a Goal amount and is Active

If you have more than one active campaign with a goal, click the dropdown button on the campaign section of the dashboard to select a different campaign to display. The campaigns are displayed based on their order in Settings. To change the order, go to Settings > Campaigns, and manually click and drag the active campaigns and drop them in the order in which you wish them to appear.
