Can’t edit field information under Orders

Hey!
We are in the process of creating a new website for a client, and are exporting an old WooCommerce database. They have used your plugin to handle checkout fields, and we have bought the Pro edition to do the same.

One issue, we have setup everything so it matches from the old site to the new, but whenever we run through and order (or open one of the older ones) we cannot edit, or even see the checkout fields within the order. We can do this no problem on the old site. So the question is, what have we done wrong, and how can we activate whatever handles the ability to see and edit the input of the fields on an order basis?

All the best,

Dannie
