Hi,
Well, that's the vendor dashboard. So you only see the information related to the current vendor.
It's not meant to display the information of other vendors.
Regardless of how you turn this around, using the backend dashboard on the frontend, or modifying the frontend dashboard to take into account the data of the other vendors and not just the current vendor, it will require development. And it's not just 2 lines of code to add somewhere so I can't give you a ready made solution here.
That's why I offered you our services for that capability.
