Can't mark a card as invalid, the button is gray and un-clickable
Hi, I'm trying to mark a card as invalid, I already try to charge the room 6 times and didn't pass. The button to mark the card as invalid doesn't work, is gray and un-clickable, and when I try to directly cancel the reservation because the card is invalid it shows in a red square that the cancel couldn't be made, to try again in a few minutes. I been trying several times in different days. It is the only reservation that I found this problem.
