Additional Info broke my checkout button. What's wrong?

Hi I added “additional info” element to my checkout page to collect phone numbers at checkout. However after adding it to the page it seems to have broken my checkout “place order” button. The button no longer works.

After removing the additional info element the button started working again.

Anyone know what’s going on here? Are there any additional settings I need to link/enable to make it work? I would still like to collect phone numbers at checkout if possible.
