Scheduler works but the editor incorrect when reopening

Hi everyone, I tried to utilize the new scheduler component. It seemed to works as expected, until I notified my automation is not in synchrone with the schedule. I realized if I create a timespan which starts at a half an hour or end at a half an hour then reopening the editor its extend to the whole hour.
I updated my dock image to the latest now I don’t see any timespan at all, althouht the automation still work. ;(
