Now I do presume that the issue is also on the js embedded form and that it is not happening for you on your Internet Explorer when going to the form directly.
Can you please check if you experience the same issue when going directly: https://secure.jotformpro.com/form/52716511964963 if not, then it will work for you as soon as you change the embed method as mentioned on your other thread.
If not, do let us know the version of your Internet Explorer for us to check on the same.
