Payment Method Registration Errors [Error Code 401 and 601]

[Najara]

For some reason the only option I'm getting is to use the Steam Wallet payment(I bought the game using Steam back in February, but used Crysta to pay for the subscription last month during March.) I thought I'd use the same steps this month and added crysta onto my account but there's no other payment options.

Is there something missing or wrong? If this is working as intended, then I want a refund, as well as some sort of notification that Steam accounts cannot use Crysta for their payment method(which is just ridiculous.) please fix this, SE.
