If the tags were applied by an import (or batch) then I see no reason not to remove them as a batch.

If part of an import they might ... but only might ... not have that information in the import.

That would have been better added as a note saying import x does not have information on x, y, z for this feature.

But *=unknown is very unhelpful.
