Hello Mohammed,

 Your are right, the tree view show amount_total_signed (total) and residual_signed (To Pay). these two fields show the amount with the invoice currency so the total amount will be incorrect. 

So what you can you do is inherit the view and doing the below:

-  hide the total.

-  Replace or add the above fields with fields which shows amount with company currency (in these fields you can add total):

         amount_total_company_signed

         residual_company_signed
