Gaming I can't "add the remaining funds" when buying a game on the eShop

[Vipera]

I wanted to buy a cheap 1.99€ DSiWare game on the 3DS eShop but the button "add the remaining funds" doesn't appear. They expect me to add 10€ for a 2€ game.
I also tried it with a bunch of other games, 3DSWare too, and they act the same.

Wtf?

Nope :/ no "mancanti" button in my screen. Just the 10, 20, 60 and 130€ ones.


EDIT: Now it works o.O

Get this... if you look up for a game on the search engine and then try to buy it, the button won't show up. Then I added it to my wishlist, exited and clicked on my Wishlist instead of searching it, and the button was there! Wtf.
