slim backup alarm

Hello,
I have Logitech Media Server Version : 7.9.2 - 1578996832 and 3 picoreplayers (Modèle platine : SqueezeLite - Type platine : squeezelite - Micrologiciel : v1.8.7-1052)
Wake up alarms are installed with Radio starting @ 7:00 am.
Since some time, the radio channels are replaced by an alarm (Image is a bird corresponding to slim backup alarm )
What is the reason for this annoying situation ?
Any help will be greatly appreciated.
Regards
