TOTAL SALES REVENUE IS NOT SHOWING IN PRIMARY CURRENCY WHICH IS USD

So basically what is happening is that whenever i receive payment in any other currency, rather thatn showing the total sales in a PRIMANY CURRENCY BY AUTOMATIC CONVERTION, IT JUST ADD UP THE NUMBER AND DOESN’T DO ANYTHING.
So, for example i sold 2 same products of 100$
so the total sales should be 200$
but because one bought it in USD and another bought it in AUD, ( which is 143.86AUD for 100USD ).
It will just add up both and show 243$ in sales which is FALSE.
IT should automatically convert it in a primary currency to show correct info but that is not happening and it is creating a lot of issue while maintaining data.
THERE IS NO ISSUE ON FRONT END OR WITH PAYMENTS, THOSE ARE WORKING PERFECTLY FINE. the issue is with just at showing the amount and just adding it up directly rather then converting it into primary currency to represent real numbers.
