Gallery Cards have all green fields but Approval button is not active


#1

Hello,
I’m trying to get approval for our domain seen.co, that has been approved already for Summary cards and Large Image Summary cards. However, after I submit a page to the validator, and all fields are marked green, I still can’t click the “Request Approval” button, which keeps being grey.
Is there anything I’m doing wrong?
This is one page I’m using for testing:
http://seen.co/event/london-fashion-week-ss14-(day-3)-london-uk-2013-112/

Also, images are all there, they also load if I navigate to their URL with my browser, but still they sometimes appear as white spaces in the card.

What do you think am I doing wrong?
