Restart message not visible on Mac OS 10.13.x after snoozing

I have a job for some Macs that requires a restart. The job is set to put up the restart message, allow snoozing, and remain on screen persistently after 24 hours has elapsed. The initial restart message shows up, but after snoozing the restart message apparently relaunches, but isn’t visible anywhere on the Mac. The only reason I know it reappears after snoozing is because when I go to restart the Mac via the Apple menu, the BES restart screen is visible momentarily after the main desktop window closes. Is anyone else seeing behavior like this?
