I set a certain ringtone for alarm. It shows what I've setup. Also saves it. But some mornings the the sound of alarm is the call ringtone but not the alarm ringtone I had set.
When I check alarm settings it still shows the alarm ringtone.
I don't know if I am doing anything wrong ou there's a bug.
Can I ask if you are using the Stock Clock app or if you're using a downloaded one?
