If len(config_scopes) >= 2, all "added" configs will not be shown in green when printing configs.

[HenryZhou19]

The problem is described in the issue title.

Here are some clues.

In sacred/config/utils.py:

def chain_evaluate_config_scopes(config_scopes, fixed=None, preset=None, fallback=None):
    fixed = fixed or {}
    fallback = fallback or {}
    final_config = dict(preset or {})
    config_summaries = []
    for config in config_scopes:
        cfg = config(fixed=fixed, preset=final_config, fallback=fallback)
        config_summaries.append(cfg)
        final_config.update(cfg)

    if not config_scopes:
        final_config.update(fixed)

    return undogmatize(final_config), config_summaries

The second one in config_summaries will have no "added" configs as final_config has been updated in the first one.

In sacred.initialize.py:

def get_config_modifications(self):
    self.config_mods = ConfigSummary(
        added={key for key, value in iterate_flattened(self.config_updates)}
    )
    for cfg_summary in self.summaries:
        self.config_mods.update_from(cfg_summary)

Then self.config_mods here will have no "added" configs as "self.added &= {join_paths(path, a) for a in added}" In sacred/config/config_summary.py.
