Route: fillter in UseRoutes excludes the majority of my routes

[lordfeck]

I see this line in UseRoutes:

var conventionalRouteEndpoints = endpointDataSource.Endpoints.Where(e => e.DisplayName.StartsWith("Route:"));
It is filtering out the majority of my routes when defined using app.UseEndpoints() which do not have a display name beginning with Route, rather they begin with my project's namespace:

The result is that I see only two routes out of the dozens in my application.

For reference my routes are declared thusly in Program.cs:

    // Configure the router
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
        endpoints.MapControllerRoute(name: "areas", pattern: "api/{area:exists}/{controller=Reception}/{action=Index}/{id?}");
        endpoints.MapControllerRoute(name: "default", pattern: "api/{controller=Home}/{action=Index}/{id?}");
        endpoints.MapRhbIdentityApi<User>();
   
        // Pass the conventional routes to the generator
        ConventionalRoutingSwaggerGen.UseRoutes(endpoints);
    })
