I am creating an Adaptive Form Template in AEM 6.2 by following this Tutorial Creating and Customizing an Adaptive Form Template in Adobe Experience Manager | I am facing an issue with the structure drop down. Options in the drop down are not visible. PFB the screenshot.

Expected Options are: 1) Structure and 2) Initial Content. as shown in the below screenshot.

Could anyone help me in resolving this issue.
