EF Core 3.1 Identity model customization - What did I do wrong?

Not sure what I am doing wrong and why it is creating double navigation for each table. I am reading the guidance from https://docs.microsoft.com/en-us/aspnet/core/security/authentication/customize-identity-model?view=aspnetcore-3.1.

This has been driving me nuts and I need to resolve this before going live next week.

Any help would be much appreciated.

Entities:

public class AppUser : IdentityUser<long>
    {
        public bool HasResetPassword { get; set; }
        public DateTime? LastLogIn { get; set; }
        public DateTime? DateRegistered { get; set; }
        public DateTime? RegistrationDate { get; set; }

        public override string ToString()
        {
            return UserName;
        }
        public virtual ICollection<AppUserClaim> Claims { get; set; }
        public virtual ICollection<AppUserLogin> Logins { get; set; }
        public virtual ICollection<AppUserToken> Tokens { get; set; }
        public virtual ICollection<AppUserRole> UserRoles { get; set; }


    }
    public class AppRole : IdentityRole<long>
    {
        public string Description { get; set; }
        public virtual ICollection<AppUserRole> UserRoles { get; set; }

        public override string ToString()
        {
            return $"{Name} - {Description}";
        }
    }
    public class AppUserRole : IdentityUserRole<long>
    {
        public virtual AppUser User { get; set; }
        public virtual AppRole Role { get; set; }
    }
    public class AppUserClaim : IdentityUserClaim<long>
    {
        public virtual AppUser User { get; set; }
    }

    public class AppUserLogin : IdentityUserLogin<long>
    {
        public virtual AppUser User { get; set; }
    }

    public class AppRoleClaim : IdentityRoleClaim<long>
    {
        public virtual AppRole Role { get; set; }
    }

    public class AppUserToken : IdentityUserToken<long>
    {
        public virtual AppUser User { get; set; }
    }
