Mixed appsettings.json & appsettings.development.json

I seem to be getting results from both appsettings.json and appsettings.development.json when I use the following:
var users = _configuration.GetSection("AdministrationUsers");

my appsettings.development.json is like:

"AdministrationUsers": [
    {
      "Email": "Development@somewhere.com",
      "PasswordHash": "AQAAAAEAACcQAAAAEJqwmeQsHrAZySU8kIV8BJPsEGirVXddDhU0EWabuGdGzNj93/9MXQ17hsFhRENbqA=="
    }
  ]

whilst my appsettings.json is like:

"AdministrationUsers": [
    {
      "Email": "Production@somewhere.com",
      "PasswordHash": "AQAAAAEAACcQAAAAEJqwmeQsHrAZySU8kIV8BJPsEGirVXddDhU0EWabuGdGzNj93/9MXQ17hsFhRENbqA=="
    },
    {
      "Email": "Support@somewhere.com",
      "PasswordHash": "AQAAAAEAACcQAAAAEJqwmeQsHrAZySU8kIV8BJPsEGirVXddDhU0EWabuGdGzNj93/9MXQ17hsFhRENbqA=="
    }
  ]

With ASPNETCORE_ENVIRONMENT set to Development and using the default CreatedDefaultBuilder and no other settings - I see the Email for Development@somewhere.com AND the Email for Support@somewhere.com - suggesting the list that is built up seems to be shared. I.e. I would expect the results (i.e. the entire collection) to have come from only one of the files - but maybe that is how it's supposed to work - if so, perhaps the configuration docs need an update pertaining to collections.
