After installing the latest patch of Adobe Acrobat DC reader, barcode is missing and left blank.

After installing the latest patch of Adobe Acrobat DC reader, 1D barcode is missing and left blank in our produced PDF form using Adobe software and our customer need to downgrade the verison of Adobe Acrobat DC reader to show the barcode. May I know if there is a bug in the latest patch or Adobe removed the support of 1D barcode for some reason? Will it be fixed in later patch?

Please advise. Thank you.
