Re-enabled alarm not going into alarm pipeline

Version 8.1.32

When an alarm becomes active it enters the alarm pipeline. After it is acknowledged it leaves the alarm pipeline, but stays as an acknowledged alarm. Then, if the alarm is disabled, it goes out of alarm. When the alarm is re-enabled it goes back into an unacknowledged alarm condition. BUT it does not re-enter the alarm pipeline. I think it should. Is there a setting I have wrong or it this a bug?
