Why can I not see the image at the top when I preview this form?

The issue seems to be related to all the errors in your conditions page.

I cloned and tested your form and initially, I did not see the image at the top of the form. But when I disabled all the conditions with the errors, I got to see the image:

Hence either diable the conditions or rectify the errors.
