DASHBOARD "Overdue Customer Balances" by different salesman

[ALEXSHEN]

Now I found other problem.

Normally our Dashboard "Overdue Customer Balances" only showing the Customer some invoice not paid. Last time, I also asked here and changed script, then it show all Customer even they paid, this is very useful for me.
   

But if the Customer have two branches, the total amount were double counting. Please see attached photo.
   
I don't know if this error is caused by changing the Dashboard display options or something else?

So now have two things
1- One Customer two branches, total amount double counting.
2- One Customer two branches cannot allocate to each sales people, everybody can see.
