Added tax on some orders?

I have a super interesting problem affecting every one that makes an order with “Klarna payment gateway” trough our client’s website. We got two payment methods, either pay directly using Bambora (Visa and Mastercard) or trough invoice with Klarna. All orders using Bambora is fine.

The tax setting is setup as “prices inclusive of tax” and it seams fine everywhere when the payment is done, but in the order details it says “price + tax” as total, when it should be “price with tax” as total.
‘
For example, our tax rate is 25% so if a person buying an item for 100 SEK the order details when buying with klarna is 125 SEK instead of item 80 SEK and Tax 20 SEK. but it’s only when Klarna have been used as payment.

Is there any way to solve this as it works perfectly using Bambora, at the moment I’m figuring we might just remove Klarna as a payment option as it makes all reports show wrong details. I’m not even sure the receipt is showing the correct details.

If anyone have an idea about how this happened or how this happens i would be glad to fixit, and I’m also figuring if i should contact these clients on the behalf of this issue as the receipt might show the wrong details.

Great regards,
Mattias Magnusson.
