I can't schedule two jobs to run every minute

Today I just started using bull as my first job schedule library. Currently, I'm just playing with it and I faced a wired situation.
I have a simple queue that just prints the job id. I registered for two jobs with different data that should run every minute. I expected to see two ids every minute but just one id prints. it's like the second job didn't schedule at all. can you explain to me why this happens?

const queue = new Queue("my queue");

queue.process(function (job, done) {
  console.log("job.id: ", job.id);
  done();
});

queue.add(
  data1,
  { repeat: { cron: "* * * * *" } }
);

queue.add(
  data2,
  { repeat: { cron: "* * * * *" } }
);

I found the problem. bull doesn't create a new (repeatable) job if another job with the same repeat time exists.
