Biblio: import file exported by "node export"

Hello Ron

after applying the "patch" described in http://drupal.org/node/826506 (deleting cid, function biblio_node_export_node_alter) I can see in the DB that authors are created. But they don't show up when viewing a node.
When comparing DB tables in (source and destination) I see that in destination-table "biblio_contributor" all values in column auth_category are set to 0. In the source table the value in auth_category are publications of those in auth_type.
After

update biblio_contributor set auth_category=auth_type;

everything looks fine.

I hope this isn't an old issue ...
