I use an extension called FireGento GermanSetup which adds variables like IBAN and SWIFT etc. I changed the SWIFT variable to BIC and now I would like to show BIC in the payment infos which are used in every transaction email and PDFs.
I changed the SWIFT label to BIC here:
The field in the backend in now labeled with BIC which is good but it doesn't seem to work for transaction emails.
When I open a Transaction email preview in the backend. It still shows SWIFT instead of BIC.
