Alarm goes off every 15 mins From 6am M-F when no alarm set

Hello,

this has been driving me crazy for months and I have noticed similar questions in the past but no answers!

my alarm goes off at 6am, 6.15am, 6.30am then 7am every Monday to Friday. I do not have any alarms set at those times and no alarms unset with these times on the clock app.

everything is turned off on the bedtime part and I have also turned off the part on settings for the reminder app.

nothing I have tried has fixed it. The notifications come up every single Monday to Friday and if I’ve been awake when they have went off I have clicked on them and they take me straight to the clock app and show me my alarms, none of which are ever set between 6am-7am.

if I put my phone on do not disturb overnight, then it won’t go off at these times with sound but it will show in my notifications that they were there. My normal alarms will wake me during do not disturb but these ones don’t.
