HANA Attributes not visible in Design Studio

Hello Experts,

We are using Design Studio 1.3 on top of HANA SPS07 on aws(cloud).

After connecting the Design Studio to HANA,and selecting a DataSource for an Analysis application,we can only see HANA measures in the application but none of the attributes.

I have checked the Attributes in my HANA views and none of them are 'Hidden' and type of views are selected as 'Cube'.

Can anyone suggest a setting or a corrective measure for this problem.
