Localization Addon is imported for an APS Application.
In CCPv1 the Application's description on the Home page is not localized and the default locale is used for these values instead.
The locale will be applied if it's included in the package.
The issue is acknowledged as POA-115464.
If possible - contact Application Packager in order to include the required locale in the default package shipping.
Contact your Technical Account Manager to trace the status of the issue.
