If you stop the scheduler and double click on the job (i.e. the line that starts "NGC 7000 Scheduled 1/45 ..."), is the twilight restriction checkbox checked again?
If that is the case, then it is "working as intended" and here's what's happening:
The twilight restriction is stored as part of each scheduler job. Once a job is setup and added to the scheduler's job list, unchecking the twilight box below would have no effect. To make that change you would need to double click on the job to signal you want to edit it, then uncheck the twilight box, then click the "Apply Job Changes" check box (the plus sign to the right of the magnifying glass becomes a checkbox when you are editing the job). If you are storing that job for re-use, then you'd also want to save it at that point. This same UI is used in the capture tab.
