'Entity Framework attempting to add records to wrong table [closed]

I have never had an issue with Entity Framework attempting to save to the wrong table before. However, today I've run into this issue.

I am attempting to save to a table called dbo.Accounts in SQL Server and for some strange reason, the SQL that it creates is the following.

DECLARE @inserted0 TABLE ([Id] int, [_Position] [int]);

MERGE [Accounts] USING (
VALUES (@p0, @p1, @p2, @p3, 0),
(@p4, @p5, @p6, @p7, 1),
(@p8, @p9, @p10, @p11, 2)) AS i ([CreateDate], [LastUpdated], [Name], [ParentId], _Position) ON 1=0

WHEN NOT MATCHED THEN
    INSERT ([CreateDate], [LastUpdated], [Name], [ParentId])
    VALUES (i.[CreateDate], i.[LastUpdated], i.[Name], i.[ParentId])
    OUTPUT INSERTED.[Id], i._Position
    INTO @inserted0;

SELECT [i].[Id] FROM @inserted0 i
ORDER BY [i].[_Position];

INSERT INTO [AspNetUserRoles] ([RoleId], [UserId])
VALUES (@p12, @p13);
',N'@p0 datetime2(7),@p1 datetime2(7),@p2 nvarchar(100),@p3 int,@p4 datetime2(7),@p5 datetime2(7),@p6 nvarchar(100),@p7 int,@p8 datetime2(7),@p9 datetime2(7),@p10 nvarchar(100),@p11 int,@p12 nvarchar(450),@p13 nvarchar(450)',@p0='2022-01-27 11:19:59.5774258',@p1='2022-01-27 11:19:59.5774300',@p2=N'Test Account',@p3=1,@p4='2022-01-27 11:24:37.7412127',@p5='2022-01-27 11:24:37.7412136',@p6=N'test',@p7=1,@p8='2022-01-27 11:28:45.9794153',@p9='2022-01-27 11:28:45.9794169',@p10=N'test',@p11=1,@p12=N'5d0f3665-110a-4986-9bbf-3f2b7da0ccbf',@p13=N'db9f3ebb-3e0d-4972-a8f9-c7cdb10ed94f'

As you can see it's attempting to save the account, AND trying to create a UserRole.

The exception is the following:

And the code that I am calling:

    // Repository
    public override async Task<Account> CreateAsync (Account entity, CancellationToken token)
    {
        entity.CreateDate = DateTime.Now;
        entity.LastUpdated = DateTime.Now;

        if (entity.ParentId == 0) 
            entity.ParentId = 1;

        Context.Accounts.Add(entity);

        var a = await Context.SaveChangesAsync(token);

        return entity;
    }

    // ApplicationDbContext
    public virtual DbSet<Account>? Accounts { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        
        modelBuilder.Entity<Account>()
            .HasMany(x => x.ChildAccounts)
            .WithOne(x => x.Parent);
        modelBuilder.Entity<Account>()
            .Property(x => x.ParentId)
            .IsRequired(false);
        //... other configuration
    }

    // model
    [Table("Accounts", Schema = "dbo")]
    public class Account:BaseEntity
    {
        [StringLength(100), Required]
        public string Name { get; set; }
        public int? ParentId { get; set; }
        public Account? Parent { get; set; }
        public ICollection<Account>? ChildAccounts { get; set; }
    }
    

Why would this happen with only accounts, all of the other entities work correctly? Is there something in the name Account that is causing this issue?

**Update**

In the `ChangeTracker.DebugView` I see this:
