Progress Bar widget not decreasing when you go back on a multi-page form

Hi guys,

I have progress bar on my form and the form was separated with page break,
the progress bar seems good when it going forward, but when it going backward it seems the progress bar doesn't decreasing by itself..

here the form https://form.jotform.me/60074922330447

I have to reload the page to make it zero again, any guide please..

Thank you for contacting us.

The Progress Bar widget is designed to work based on a number of answered form fields. When the form user clicks on the back button, it does not actually clear any answers, so that the progress bar is not decreasing.

If you need any further assistance, please let us know.
