Cant Update Card

I’m unsure if I’m being stupid or if this is a bug.

I was on a plan as a student, but my card expired 25 days ago. I have gone to update it but the button is missing at the bottom…
I can’t find where to put any card details now, as there is no “active” card.

Clicking the red button just refreshes the page
