While using the external import system to import my csv, the tickets now (did not happen in the past) are being imported with an "unknown" channel, which is causing one of the custom fields I have created to not display on tickets created via bulk load.
Tickets I create by cloning, or from inside JIRA, have the proper channel expressed (JIRA, Portal, etc.) and those tickets (in the same project I'm bulk loading too) will display the custom field on the ticket.
I am sure the custom field is setup correctly as this has been working for some time now, and it still displays correctly on tickets created inside of JIRA, but the failure to be able to bulk load a specific "channel" (I tried and not possible), causes the tickets to create with an unknown channel, and then this particular custom field will not display on those tickets.
