I have several jobs configured with the same schedule interval:

H/12 8-18 * * 1-5

Which basically should mean: run every 12 minutes in business hours in work days.

But the issue is that every of those jobs runs only 3 times. Like at 01, 13, 25 minutes. And none of them run in the second half of the hour.

Jenkins Version: LTS 1.565.3

UPDATE: even if I specify `* * * * *` - then `SCM Poll` scheduler does not run in the second half of every hour. In 40 minutes I will add what minute is the last run at.
