Can't update database in ASP.NET Core

I've created a table named USERGOLD using Add-Migration and update-database and it works fine the table is created in SQL Server, but now I'm creating another table FoodMenu.

I've created a model class and dbset, I used add-migration and the table is created in the migration, but when I run update-database to create the table in SQL Server, it's not working. I get an error

There is already an object named 'UserGold' in the database

I don't know why the update-database are taking my previous migrations.

Contexto:

public class RestoContext : IdentityDbContext<RestoUser>
{
        public RestoContext(DbContextOptions<RestoContext> options)
            : base(options)
        {
        }

        public DbSet<Menu> Menu { get; set; }
        // public DbSet<Employees> Employee { get; set; }
        public DbSet<Employees> Emp { get; set; }

        public DbSet<Manager> Manager { get; set; }
        public DbSet<GoldMenu> GoldMenu { get; set; }
        public DbSet<UserGold> UserGold { get; set; }
        public DbSet<FoodMenu> FoodMenu { get; set; }

        protected override void OnModelCreating(ModelBuilder builder)
        {
            base.OnModelCreating(builder);
            // Customize the ASP.NET Identity model and override the defaults if needed.
            // For example, you can rename the ASP.NET Identity table names and more.
            // Add your customizations after calling base.OnModelCreating(builder);
        }
}

My migration:

using System;
using Microsoft.EntityFrameworkCore.Migrations;

namespace Resto.Migrations
{
    public partial class AddusergoldToDb : Migration
    {
        protected override void Up(MigrationBuilder migrationBuilder)
        {
            migrationBuilder.CreateTable(
                name: "UserGold",
                columns: table => new
                {
                    userId = table.Column<string>(nullable: false),
                    Usermail = table.Column<string>(nullable: true),
                    CardNumber = table.Column<string>(nullable: true),
                    Validedate = table.Column<DateTime>(nullable: false),
                    Amount = table.Column<float>(nullable: false)
                },
                constraints: table =>
                {
                    table.PrimaryKey("PK_UserGold", x => x.userId);
                });
        }

        protected override void Down(MigrationBuilder migrationBuilder)
        {
            migrationBuilder.DropTable(
                name: "UserGold");
        }
    }
}

It seems there is a problem in migration process, run add-migration command in "Package Manager Console".

May be your question is dulicate here
