Game Notice doesn't work properly

Game Notice is not functioning correctly. It only sends the first message and does not send any further messages.
If the message frequency is changed, for example, to 5 seconds, only the first message is sent, and then nothing follows.

I noticed that if you use more than 15 lines in Game Notice, it stops working. It sends the first line once, and that's it.
