VAT Number in user profile

Hello, I like this plugin. It seemed to pull in the VAT number from the User profile into the billing information before, but no longer does this. Was this a feature of the plugin before. For my customers who have a VAT number I have added it to their user profile. I then create new orders for customers, and at one stage I saw that the VAT number was being pulled into the orders details under the billing information. But this has stopped. I am using flexible invoices which adds a VAT number to the billing information of the order. I don’t know how these two were able to talk to each other. But something stopped them from working together. I also have Checkout Field Editor installed however it doesn’t affect the display of the fields if I disable the field which it has found “billing_vat_number”. Your thoughts would be appreciated
