MultipleMachinesJobScheduler.RunScheduler only start first machine, after restart all machines start

[Metin-Gunduz]

I have implemented a scheduler to communicate with multiple machines sequentially. The machines are working well individually. However, I'm encountering an issue with the code below when running the scheduler:

`

   private void button2_Click(object sender, EventArgs e)
    {
        errortext = "";
        MultipleMachinesJobScheduler.RunScheduler(comm.channels.Select(x => x.machine).ToList(), async (machine, scheduler) =>
        {
            scheduler.From(machine.Id + ".From", machine, MachineDataType.CommunicationTag).Result.Query(machine.Id + ".ConsoleQuery", QueryConsole).Result.To(machine.Id + ".To", machine).Result.Deal(machine.Id + ".Deal", OnSuccess, OnFailure).Result.Run();
        },
        -1, 0);

    }
    private void button3_Click(object sender, EventArgs e)
    {
        MultipleMachinesJobScheduler.CancelJob();
    }

`

Issue Description:

• On the first button click, only the first machine in the array starts communicating, whereas all machines are expected to start.
• Without making any changes to the code, if I run function (click the button) again, all machines start communicating as intended.

Expected Behavior:

• All machines in the array should start communicating on the first button click.

Environment:

• Scheduler version: v1.4.3
• Development environment: Visual Studio 2022

Question: What could be causing this behavior where only the first machine starts on the initial click, and how can I ensure that all machines start communicating on the first run?
