"rhsm_username" in "Virt-who configurations" is blank.

Issue

I generated the virt-who conf file from the Satellite's "Virt-who configurations".
but,"rhsm_username" in "Virt-who configurations" is blank.
Normally rhsm_username is set to the automatically generated virt-who-reporter-*.

Satellite WEBUI > Infrastructure > Virt-who configurations >

rhsm_hostname=satelltie.exam.com
rhsm_username=
rhsm_encrypted_password=$user_password
