Wht S10 clock alarm uses incoming call ringtone, rather than the selected alarm ringtone

[Android Central Question]

Why does my S10 Samsung clock alarm function, use my main incoming call ringtone, rather than the selected alarm ringtone?
Having just upgraded from the S8, this issue has occurred. I'm not sure if it's due to having a downloaded non-defalt ringtone for incoming calls, or a sleep function.

Did you select the alarm tone in the alarm clock settings, or in the general phone settings. (Some apps have to have their own settings set, or they pick up something you don't want, like the alarm clock picking up the ringtone instead of the alarm tone. Try setting the alarm from the settings in the alarm clock.)
