I have a Jenkins job (JOB_A) with schedule set to "H H(3-4) * * * ", and it was running fine for a couple of months. Recently, I changed the schedule to "H H(4-5) * * * "
Since then, I notice Jenkins kick off two copies of JOB_A. One was kicked off at 3-4, another one was kicked off at 4-5

I did the following experiment:
1) rename JOB_A to JOB_B
2) Disable JOB_B
3) execute: java -jar jenkins-cli.jar -s http://<jenkins server>:8080/ list-jobs to ensure JOB_A is not in the list
4) after 24 hours, check the jenkins log, /var/log/jenkins/jenkins.log
I notice JOB_A has been kicked off.

I did some google search, but cannot find anyone has reported an issue like this one.
Any idea how to remove the hidden job (JOB_A in my case)?

thanks
