Enqueued Job being run continually( Repetitively )

bug?
1

Hi, i have added multiple jobs in Enqueue method. Job should enqueue only once. But here Execute method is running multiple times.
If i have only one job in Enqueue method, then Execute method is running only once as i expected.

How to add multiple jobs in Enqueue method,but all the jobs should run only once?
or
Is there any other way to run multiple jobs in a single job? because All the jobs are not in a single solution. All are in different project. But i have to run all the jobs in sequence manner.

PFB the code

public static void Enqueue(string x, string y)
    {
        try
        {
            var jobId = BackgroundJob.Enqueue<Test1>(x => x.Execute(JobCancellationToken.Null, x, y));
            Logger.Debug($"enqueued job: {jobId}");

            jobId = BackgroundJob.Enqueue<Test2>(x => x.Execute(JobCancellationToken.Null, x, y));
            Logger.Debug($"enqueued job: {jobId}");

            jobId = BackgroundJob.Enqueue<Test3>(x => x.Execute(JobCancellationToken.Null, x, y));
            Logger.Debug($"enqueued job: {jobId}");
        }
        catch (Exception ex)
        {
           
        }
    }


 [Queue(JobSettings.Queues.Core)]
    [LogJobFailure]
    [DisplayName("Test")]
    [DisableConcurrentExecution(600)]
    [AutomaticRetry(Attempts = 0)]
    [ProlongExpirationTime(7)]
    public void Execute(IJobCancellationToken token, string culture, string brand)
    {
        Enqueue(culture, brand);
    }

Thank you.
