iDeal Symbol missing

When I try to checkout… there are no payment options available.
I think it’s a CSS problem though. I only want iDeal as a payment option.
With a problem from another company there’s not any problem at all but I rather work with your plugin because I love the dashboard of Mollie.

Thanking you in advance,
Kitty Knol
