3595273 - Duplicated Tiles issue in Fiori Launchpad for Pages and Spaces

As a designer or system integrator, we are using Fiori Launchpad Layouts by creating a custom Space and a custom Page for multiple business roles, mapping the required Tiles on the Page from multiple custom business catalogs according to the role context. When we perform a Page preview in the 'Manage Launchpad Pages' application, the preview displays the correct set of tiles based on the role context. However, when we tested it by assigning the Business Roles to the end user, we encountered duplicate tiles in the user's Fiori Launchpad.

Pseudo explanation:

Let the following be true.

User
|____Custom Space and Page X
       |___Business Role 1  ---> Multiple Catalogs
       |___Business Role 2
       ..
       ..
       |___Business Role N

When doing a Page Preview, it appears to have the correct set of tiles mapped based on the role context.

But 

When assigning a Business Role to X user -> this user has duplicated tiles.
