Crysta needed for Payment not properly showing up

Good evening.

I've been having this issue since Mog Station was released, but I decided to wait before asking hoping it might get fixed. ...Let's see if I'll make a faux pas by missing some obvious stuff...

When I try to Subscribe and pay, I get this:

For the 30, 90 and 180 days subscriptions, it lists “Crysta Cost: 0”, and that's the problem, because I'd like to know how many Crysta I need.
If I click on the below “Subscription fee structure”, the required money is listed, but only monthly, so for the 90 and 180 days subscription I don't understand if I've to count the required money by myself and only then buy the required Crysta.

I wanted to pay for the 90 days subscription but it lists only the monthly cost. 8,99 € for 90 days is 26,97 €, while 7,99 € for 180 days is 47,94 €. So that means I'd have to buy either 2697 or 4794 Crysta.

I just wanted to know if that “Crysta Cost: 0” is normal and will fix after I buy the Crysta after the calculations I did.
Is anyone else having the window appear like that? :confused:
