Hi! Did you create the invoice before making these changes to the settings? Once a document has been generated it will not automatically update with the new settings unless you delete it and re-create it. This is important because you don’t want your existing invoices to change when you change your company name or if you change addresses.
You’ll see that if you create a invoice for a new order it will actually use the updated company name settings.
Additionally, under WooCommerce > PDF Invoices > Documents > Invoice, there is an option “Always use most current settings”, which you can use during testing (although I recommend disabling it on a live website so that invoices remain immutable).
Let us know if you need more help with this!
