Appsettings not mapping to Options class

I could probably have worded the question better, but please bear with me. Also, this is not my code, and probably has not been set up properly, but other team members are all really busy.

I see this in the

Program class:

        public static IWebHost CreateWebHostBuilder(string[] args)
        {
            var config = new ConfigurationBuilder().AddCommandLine(args).Build();
             return WebHost.CreateDefaultBuilder(args)
...
                     .UseConfiguration(config)
                     .Build()
                     .InitializeIdentityDb<ApplicationUser, ApplicationRole>();
        }

        public static IWebHost CreateWebHostBuilder(string[] args)
        {
            var config = new ConfigurationBuilder().AddCommandLine(args).Build();
             return WebHost.CreateDefaultBuilder(args)
...
                     .UseConfiguration(config)
                     .Build()
                     .InitializeIdentityDb<ApplicationUser, ApplicationRole>();
        }

        public static IWebHost CreateWebHostBuilder(string[] args)
        {
            var config = new ConfigurationBuilder().AddCommandLine(args).Build();
             return WebHost.CreateDefaultBuilder(args)
...
                     .UseConfiguration(config)
                     .Build()
                     .InitializeIdentityDb<ApplicationUser, ApplicationRole>();
        }

        public static IWebHost CreateWebHostBuilder(string[] args)
        {
            var config = new ConfigurationBuilder().AddCommandLine(args).Build();
             return WebHost.CreateDefaultBuilder(args)
...
                     .UseConfiguration(config)
                     .Build()
                     .InitializeIdentityDb<ApplicationUser, ApplicationRole>();
        }

and then

` is defined as such:
```cs

            using (var scope = host.Services.CreateScope())

                var services = scope.ServiceProvider;

Then

CassandraOptions

 is declared as:

        public bool DurableWrites { get; set; } = true;

Now at my breakpoint on
