Blockcerts cert-issuer issues

After I run this command --> cert-issuer -c /etc/cert-issuer/conf.ini

it shows

But it doesn’t show in data/blockchain_certificates folder. Can anyone help me? Thanks

This has never occurred to me… Besides, it says that the transaction has been broadcast but I can’t find it.
Perhaps someone else here has already experienced this?
