Tuen,
I don't like saying I told you so, but you didn't expect it to work properly first time.
I think "half baked" is the proper terminology.
Give it another couple of releases. Before then I'd use AcadM and MDT to import Inv files and then annotate them before saving as DWG.
Sorry I couldn't be of more help
