Default [Q] Alarm clock icon in notification area disappearing

Hello,

The Alarm Icon in the notification area keeps disappering, specifically it never remains in the notification are after a reboot.
The alarms themselves do work and do go off at the given time, but the icon isnt showing.
After a fresh reboot the icon appears briefly when the system is loading, but disappears once system fully loaded

any advice on how to remedy this is appreciated

PS: google search led me to two alleged solution of which NONE worked for me. One suggested to clear data for the clock app. The other suggested that this issue is related to the Pandora app messing things up (I have never installed such app)...
