Key Figures Hierarchy behavior

Hello Experts,

We are facing Problem with Key figure Hierarchy.

The arrow when down was supposed to hide the details and when on the right to display the details.

That Means When Hierarcy values are Hidden Arrow should show in Down direction.

When Hierarchy values are displayed Right Arrow should whow in Right direction But here it is happening in Reverse direction.

Could you please help us to solve this issue.

Thanks And Regards

Venkat
