**Ignition version :** 8.1.29  
**Operating system :** Linux | amd64

**Problem encountered**  
Our customer complained about alarms in the alarmlist that remained in the alarmlist while the alarm was not present anymore

1. KLA07 has a tag 'defect' with one configured alarm :  

2. Alarm settings :  
the alarm is active when defect has the value : 1  

3. the AckTime was \> ActiveTime, the value was 0, but the clear time was still 'null'

**Question**  
Has anyone seen such behaviour, and could this be a bug  
could it be that the the clearing event was missed by the system?

**How we temoprarily removed the alarms**  
To remove the alarms we had to resort to invers the setpoint (equal to 0) of the alarm to trigger the alarm, and then set the setpoint again to it's normal value (equal to 1) which resulted in the removal of the said alarm from the alarmlist
