Table not syncing in app while others are

[tanakamawere]

I have a table that is based on the following base entity

public abstract class TimerEntity
{
    public int Id { get; set; }
    public string Name { get; set; } = string.Empty;
    public Guid UserId { get; set; }
    public Guid CategoryId { get; set; }
    public Category Category { get; set; } = null!;

    // Tracks the current state of the timer
    public TimerState State { get; set; } = TimerState.Stopped;
    public DateTime CreatedAt { get; set; } = DateTime.UtcNow;
}
public enum TimerState
{
    Stopped,    // Timer is not running and can be started
    Running,    // Timer is actively running
    Paused      // Timer is paused and can be resumed
}

This class is inherited in the following classes

public class SimpleTimerEntity : TimerEntity
{
    public TimerMode Mode { get; set; } = TimerMode.CountUp;

    // Sync-friendly properties (stored in database)
    public long ElapsedTicks { get; set; }
    public long? GoalDurationTicks { get; set; }

    // For resuming after pause
    public DateTime? LastStartedAt { get; set; }
}

public enum TimerMode
{
    CountUp,    // Stopwatch
    CountDown   // Countdown from GoalDuration
}

And

public class PomodoroTimerEntity : TimerEntity
{
    public int CompletedSessions { get; set; }
    public PomodoroState CurrentState { get; set; }

    // Sync-friendly properties (stored in database)
    public long WorkDurationTicks { get; set; }
    public long ShortBreakDurationTicks { get; set; }
    public long LongBreakDurationTicks { get; set; }
    public long RemainingTicks { get; set; }

    public int SessionsBeforeLongBreak { get; set; }

    // Runtime tracking
    public DateTime? LastStartedAt { get; set; }
}

public enum PomodoroState
{
    Work,
    ShortBreak,
    LongBreak
}

I have this configured in EF to use one table as follows

    public DbSet<TimerEntity> Timers { get; set; }

//then 

        modelBuilder.Entity<TimerEntity>()
            .HasDiscriminator<string>("TimerType")
            .HasValue<SimpleTimerEntity>("Simple")
            .HasValue<PomodoroTimerEntity>("Pomodoro");

And when I sync, it doesn't sync any data to the MAUI client on this particular table while other tables are working...
