Exporting personalized meta data

Hi

I use the plugin WooCommerce Product Add-on to allow my customers to write down the name or initials they want to add to their product (so it can be printed on the product).

When I export my orders using your plugin, this extra detail isn’t included in the output so I was wondering if you are able to help?

I have seen there is a way to add a custom field for export but when I try adding my personalisation meta (i think that is what my meta key is called) it doesn’t show up anything.
