I think I see where the problem is happening.
when you select the form, the property inspector has options to Edit the Form, Edit the Design, Edit the Contents
If you select to Edit the form, it looks like it is causing the Jquery Options code block to duplicate, after it duplicates a few times, it starts to duplicate above the jquery script tag causing the form to fail.
I Have logged this behavior as a bug so we can correct it in the next update.
to work around the bug, use the Edit Form Contents access point on editing the form rather than using the Edit Form button.
If you still need help with this, let me know and I Will call tomorrow.
