This is a problem when opening the downloaded CSV file via Microsoft Office Excel and the currency is not USD. Opening this file using other app like Google Sheets will show the currency properly.
​
Instead of opening the file directly in Excel, you should try creating a new excel file and importing the downloaded CSV into it.
