Alarm stuck in Alarm Status Table

I have two alarms of exactly the same tag, same alarm, stuck in the Alarm Status Table.
I have tried disabling them, making the alarm active then not active, none of this clears the two rogue alarms.
When I query the alarm event table in SQL it appears both these alarms have the clear time (eventtime) after the next active time for the same alarm. Because the alarm is so close to triggering on one of the occasions there are four active and clears for the same alarm with times actually inbetween the rogue active and clear.

How do I clear these and more importantly how can I stop this happening
