Events not executed when emergency playlist is playing

Hi,
I’m running mAirlist 6.3.24. When the playlist is running empty, an emergency playlist will be loaded to prevent silence on the radio. Unfortunately, when this emergency playlist is playing, the event to append the playlist of the next hour is no longer executed.

When it happens, I clear the playlist and load the playlist of the current hour. It would be nice that the playlist of the next hour is added automatically as expected.

Does anyone has some advice to solve this?
