Craft Commerce: Wrong payment currencies in orders

I have Craft Commerce installed on my site (which uses Craft CMS 3.5.14).

I have set up multiple payment currencies for it (NZD – which is the base currency, AUD, EUR, GBP, JPY, USD).

When I go to Commerce -> Orders -> All orders, the total price of the order is rendered as expected in the grid as shown in the picture:

But when I click on the order, the order summary always shows
in NZD even if it was paid for in another currency:

I’m not sure if this is a bug or I am missing something.

Thank you
