which yaml files to use

I installed the module on a Drupal 9 site and exported the menu.
but I get 3 yaml files.
menu_export.export_data.yml
menu_export.export_data.yml.yml
menu_export.settings.yml

the first two differ in some points. e.g.

  revision_user:
    target_id: '0'
  revision_log_message:
    value: ''

vs

  revision_user: false
  revision_log_message: false

which one is the right one to import?
