Help regarding Delivery Details ingame

Hey there,

I've been recently interested in purchasing a supporter pack that requires your delivery details ingame. I've made sure everything is filled out, and even filled it out on the website here and then confirmed, before going back to make sure the information is up to date. For whatever reason, the information does not seem to work ingame, and simply says at the bottom "An argument was invalid".

Any help with this? I really wanted to purchase the supporter pack I wanted but I wanted to do it through steam since I had some steam wallet leftover. Thanks in advance!

Sorry about that, managed to figure it out finally, you can close this up now if you'd like. Solution was to cycle the delivery details tab via the "Opt Out" Button, since it wasn't checking to see if the information in each line was updated.
