Unavailable fields on Taxon table in Workbench

Hi everyone,
By testing the import of Taxon, we see some fields on Taxon table in the Schema configuration : Full Name, Is Prefered, Is Hybrid for our example that are not available on the Workbench (even as Hidden Fields). We check on Query Builder and there are available on it so does we have something to make to get access on those Fields.
Thanks.
