AudioLabel has Disc Templates and Case Templates. The Case Template always includes a Front Cover and a Back Cover. When you click the "Edit Dimensions" button for a Case Template, the Front and Back Cover can be on the same page, or on two different pages. If the Back Cover is on the second page you might need to click the "Back" tab in the "Edit Dimensions" dialog to edit the dimensions (as shown below):
Please let me know if you need further assistance.
