Quartz Scheduler (.Net) - Why does work start immediately after running the built-in RescheduleJob method?

Question

When I start a task using Quartz, I write data to a table in my database, and I can see that when I start a task manually or schedule a task, the table is filled with tasks in the correct time order.

However, when I redirect the task using the built-in method RescheduleJob, the task starts twice; once, when I run the method, and then correctly, while the task was transferred to.

Example:

Revised task at 09:01:11 , but the task was inserted into the database twice:

09:00:23 (a few seconds after the method call RescheduleJob)

09:01:11 (transplant time)

I looked at my code and do not call anything work before moving on to the method RescheduleJob.

public void RescheduleTrigger(TriggerKey key, string cronexpression)
{
 var trigger = this.GetTrigger(key);
 var triggerBuilder = trigger.GetTriggerBuilder();
 ITrigger newTrigger = triggerBuilder.WithCronSchedule(cronexpression).Build();

 this.scheduler.RescheduleJob(trigger.Key, newTrigger);
}

I had Googled around, and I found only one such case, and it was not resolved. Has anyone come across this before and can help me get around this?

scheduler.pauseAll();
Date currentDate=new Date();
trigger.setStartTime(currentDate);
scheduler.rescheduleJob(trigger.getName(), trigger.getGroup(), trigger);
scheduler.resumeAll();

this.scheduler.UnscheduleJob(key); 

var trigger = this.GetTrigger(key);
var triggerBuilder = trigger.GetTriggerBuilder();
ITrigger newTrigger = triggerBuilder.WithCronSchedule(cronexpression).Build();

this.scheduler.ScheduleJob(newTrigger);

RescheduleJob

var trigger = this.GetTrigger(key);
var triggerBuilder = trigger.GetTriggerBuilder();
ITrigger newTrigger = triggerBuilder.WithCronSchedule(cronexpression).Build();

this.scheduler.RescheduleJob(trigger.Key, newTrigger);
