Problems with scheduled programs not playing (log)

Ubuntu : 20.04.6 LTS
Libretime ver : 3.1.0

I am attaching the log because there is a problem that the scheduled program does not play.

The audio wasn’t playing properly, so I tried the following way.

When I reboot the server, the audio in the schedule box was not played until the end.

It plays again properly as we move on to the next schedule section.

I’d like to ask what the cause is.
