Booking Form login doesn't display correctly on iPhone

My website is still in pre-prod and I am having trouble with the way the event booking for is displaying on iPhone. I can seem to find a place to correct it. You can see what I mean at https://theelysemarcuslegacyfoundation.org/events/ page and click on the test event on an iPhone. The booking form looks ok, but the login section on the right is all squished together. Any recommendations appreciated.
