Issues when use Klarna Checkout plugin

Hi, Great plugin but we also use Klarna Checkout and if Klarna i enabled it add the product from Uppsells Funnel plugin but then the Klarna refresh 2 times and the product was added is no there anymoore.

If we disabled the klarna checkout plugin and only use PayPal checkout all works fine but we have to use klarna also.
Klarna Checkout use ajax to reload all the changes so we belive maybe this is the problem.

Is it a work around for this you think?

We have make an testsite for you to check this for us and this testsite is no problem to test everything you want becuse it will be deleted when you finished to test.

Regards André
