Payment option

I get wrong size on Klarna  in checkout, I have tired to do lots of changes
but I can not get It to the right size. Its to big
I did have it as a option title, I did delete all in translate meny   pm_klarna_checkout:title_option_checkout
and still I have problem, se file :(
The keys are named a bit wrong. But they are:

Option title:

Option description:

            'name' => language::translate(__CLASS__.':title_option_checkout', 'Checkout'),
            'description' => language::translate(__CLASS__.':title_option_description', 'Invoice, installment, card, or direct bank'),
