During an import of Bugzilla data using the importer plugin, the "QA contact" field does not get imported. After an initial import via the importer plugin, I created a CSV file with "Bug ID", "Summary" and "QA Contact" fields and tried to import this via the csv importer. But the import shows errors for each of the issues I am trying to import. Is this the correct way of importing fields from Bugzilla which the importer plugin does not import?
