My form wont transition to next page

I have been using this form for 4 years now and I have not had this problem before.

I just enabled it to make the registration for the race live, but the back and next buttons are not working on my second page, the runners can not go forward to the payment portal.

We would like to apologize for the inconvenience. It appears that the issue was caused by the height of the Spacer Widget. I have reduced the Height value via the Question Properties to fix this for your form.

You may test the form again to make sure that it is working properly now.
