My form fields are all overlapping with each other in Preview

The form looks fine in the editor, but the form fields are all overlapped in the preview like this:

[Album] Imgur

What is causing this issue and how can I fix it?

Thanks!

EDIT: Also, why is Unbounce injecting a “top: 0px” property to every form field? It looks like this is what’s causing them to be stacked.

This is the code in the inspector: https://imgur.com/a/XyVVx8C
