Barcodes of the following format are not identified and cannot be extracted within FC:
This is caused by the fact that for the FlexiLayout within the document definition the "Extract post barcodes" option is not enabled
In the FlexiLayout Studio's toolbar, navigate to the FlexiLayout -> Properties -> Advanced Pre-recognition Properties button -> Advanced Tab -> Enable the "Extract post barcodes".
Match the documents in FlexiLayout, verify if the barcodes are identified, and export the updated FlexiLayout.
Apply the new FlexiLayout to the document definition and verify the results.
