Microsoft Sharepoint list and powerBI

I have a list created with the new "Microsoft Lists". One of the fields is a calculated field (called "Estimated Cost") formatted as currency. Next step is to create a PowerBI from the list itself. All works fine, except for the fact that a visual that I want to show the Estimated Cost is shown not as a currency, but as text. Any idea of what it might be wrong?

This is how the field is set in the list configuration:

Thanks
