Uninstall deprecated Actions UI removes Administrator role

My 10.4.7 drupal shows in status:

Deprecated modules installed Deprecated modules found: Actions UI.

There is this contributed module https://www.drupal.org/project/action but it's not covered by security updates.

In advance trying to uninstall Actions UI, I get:

The listed configuration will be deleted.
Action
    Add the Administrator role to the selected user(s)
    Remove the Administrator role from the selected user(s)

Role
    Administrator

If I continue, Admin role is deleted and I loose access to site.

I do not believe this is ok, and I can't remember doing anything with this module.
