Ghost alarms

I got the iPhone 11 a couple of weeks ago. Every day, several times a day I get an audible alarm going off. There is no alarm set for this time. Initially I set the phone up via iCloud. Since this problem started I have followed all the troubleshooting I can find online for it. I have turned off and erased all alarms, rebooted the phone and create new ones. Did not fix it. I have reset all settings 2x and rebooted 2x. Did not fix either time. I have erased all content and settings on phone and restored from Cloud, rebooted. Did not fix. Turned on and then off bedtime, rebooted, did not fix. Erased all alarms and left none, alarm still comes on. Created new alarms for the ghost times, turned them on, then turned them off, rebooted the phone, erased the alarms and rebooted the phone again. still the alarms come on. For instance I get an alarm every day at 9:30. No alarm exists at this time. So I created one, then turned it off. still comes on. When I click on the button to the left of the time labeled alarm, it takes me to the alarm screen where there is no alarm. So I get an alarm at this time at 9:30, the alarm goes off and when I turn it off from the main screen, it comes on again. Its like there are hidden alarms on the phone. There is nothing on calendar, nothing on bedtime, nothing on remind, nothing on the connected MacBook. All calendar events, alerts, airdrop are all set to vibrate only. Yet I still get the audible alarm. Getting quite frustrated with these alarms. I get 3 of them every day. Please tell me what to do in order to get this resolved.
