Not working with “name your price plugin”

Hi there I just created a WooCommerce “name your price” product and the currency converter seems not to work with any other currency but the default (ZA)

See screenshot where I tested with USD, and in the Cart – $0 is shown when I entered $2.

Oddly, if I set “Minimum amount” for the Name Your Price product, then it does display an amount, except then it DOUBLES it. So if you enter $2 it will then show $4…

You can test this here:

Thank you
