Hey there, thanks for posting!

Yeah this indeed seems like a bug.
In the meantime, if you re-created the parser (with all the same arguments) and used it the second time, you should have somethig that works. For example:

def get_parser(with_debug: bool = False, add_help: bool = False):
    parser = ArgumentParser(add_help=add_help)
    parser.add_arguments(ModelConfig, dest="model")
    parser.add_arguments(TrainConfig, dest="train")
    parser.add_argument('--debug', action='store_true')
    if with_debug:
        parser.add_arguments(DebugOptions, dest="debug_options")
    return parser

first_parser = get_parser(with_debug=False, add_help=False)
args, extras = first_parser.parse_known_args()
if args.debug:
    second_parser = get_parser(with_debug=True, add_help=True)
    args = second_parser.parse_args(extras)    

I've coded this up quickly just to give you the idea, this might not be exactly what you want though.
