Setting default ringtone for Alarms set by Siri

When I ask Siri to create an alarm, or a new timer for me, it is not setting it to my default ringtone. When I set a new alarm, manually, it inherits the last ringtone I use for the last alarm I set. Siri will not do the same. Ever since I migrated my Settings, it continues to set the default ringtone to what was set on my last phone, I can't change it.

How can I set the default alarm ringtone for Siri?
