Date and Time Field not working in popup

Hi Team,

I have added the fluent forms in a pop up and unfortunately the date and time is not working.

Can you please help me.

Please visit the site: https://www.greyboy.in/product/grey-bomber-jacket/

Once you are in this page you will see a button Feel & Buy

This action will show popup and unfortunately the date and time is not working. Need your help.

Thanks
Srinivas
