CJA | Currency Conversion Error

Hello everyone,

I have created a derived discount field at the product level to convert the value to negative. The field works as expected, but when I select the option to convert the currency to see the discounts in dollars (because I have information from several countries) in the project, I encounter an error. Has this happened to anyone else? Does this currency conversion option not work for derived fields, or do you have any idea what it could be?

Note: I have already done the conversion for negative values and it also works well.

Thanks, everyone.
