Setting alarm wont work.

I work retail and have weird hours and Im a VERY HEAVY sleeper. I had gotten a new phone and all of a sudden. When I set a time it keeps wanting me to verify I want to change it and that another device had set an alarm would you like to overwrite it? Yes. And it just keeps doing that, even when changing the alarm volume. PLEASE FIX I know its not the unit I had exchanged my last one to see if that would help. Same thing so its definitely a software issue
