Woocommerce advanced checkout fields not showing the entered value

I am using woocommerce-advanced-checkout-fields plugin and added a repeater field to the billing section as follows

As you can see in the image above the repeater field "Name/Email" is applicable to the product "Belt"

Now when I go to buy the product from the store and make the quantity 3 as follows the repeater field is shown 3 times and all is good to the point.

Now when I place the order the landing page does not carry the values I entered as follows

Also, the values are not showing in the Order admin section as follows.

I believe that I have clearly elaborated the problem. Need your suggestions to solve this issue
