Switch from Klarna to other payment methods

Hello!

The Klarna plugin works great, but we have some customers that don’t wont to pay with Klarna or Klarna rejectet them.
We have some other payment gateways installed and configured, but as soon as a client chooses Klarna as there Payment option, they cant switch back.

How can we fix that and let the customer choose another payment option/gateway?

Thank you very much!
