Hi,  
I’ve issued a batch of certificates from a csv files with the following additional fields, mark, grade and subject using cert-tools. I was successful in issuing it in ethereum blockchain and also I can verify them using blockcert-verifier implementation. But, the problem is I can’t list the additional fields in my certificate using the cert-web-component. Should I need to add custom fields in polymer js. I’m not familiar with it. Any help will be appreciated.
