How to reset klarna cart billing info in litium 8

How do one clear the billinginformation in klarna checkout if it has been set before?
It looks like it is possible to change the information buy updating the billing info on the cart but if we try to set billing info values to null or empty string klarna checkout isn’t updated.

It is possible to set all values to to “Fyll i dina uppgifter” but it is not possible to sett all values to “” or null

we are using cartContext.AddOrUpdateBillingAddressAsync(billingAddress) to update the cart.
and is possible to change/update but not set empty values for the fields.

The cart order is updated to empty values but not the klarna checkout.

Litium version: 8.14.2

Switching to another paymentmethods and then back atleast seems to do the trick.
