Some field are not shown

Hi,

I had to deactivate your plugin because after updating woocommerce to latest version your field weren’t visible on frontend. I discovered only because a customer of mine tried to buy a product but she get a notice that a required field must be filled while the field wasn’t shown at all.
I tried to deactivate and reactivate your plugin but this time didn’t work, so I deactivated it.
Please, make a check if you like of your plugin against latest woocommerce.
Thanks
Angelo
