Configured custom routes are not persistent

Hi there,
Looks like the issue happened in export process.
The issue is not reproducing when we export the full list of configs arising in the process of working with this module:

• multiple_registration.access_settings_page_form_config
• multiple_registration.common_settings_page_form_config
• multiple_registration.create_registration_page_form_config
• system.action.user_add_role_action.role1
• system.action.user_add_role_action.role2
• system.action.user_remove_role_action.role1
• system.action.user_remove_role_action.role2
• user.role.role1
• user.role.role2

After the configuration import, items on /admin/config/people/multiple_registration page are existed and forms are available.

multiple_registration.create_registration_page_form_config.yml

roles:
  role1:
    path: /login/role1
    url: /user/register/role1
    redirect_path: /
    hidden: 0
    form_mode_register: register
    form_mode_edit: default
  role2:
    path: /login/role2
    url: /user/register/role2
    redirect_path: /
    hidden: 0
    form_mode_register: register
    form_mode_edit: default

@gun2dru thank you for providing your test results.

You are right, starting from the module version configuration schema of the module has changed.

As I can see the issue was created on 9 Apr 2019, so a lot of changes were applied to the module from that time.

If you are using an outdated version of the module please create a DB backup before the module upgrade, then pull a new version and run "drush updb", all outdated configurations will be upgraded to the new configuration schema format.
