[RESOLVED] "An alarm could not be acknowledged. It may no longer be registered."

Hi, we had an edge system crash and on restoration we some alarm on the master system that are no longer on the edge but we can't clear them from the alarm page (or by script) and we get a
"An alarm could not be acknowledged. It may no longer be registered. Event details: 83efbca8-1430-43b0-8bf9-3281156d6b4c / {{ackUser=usr:REDACTED, eventTime=Tue Jul 15 13:53:08 SGT 2025, ackUserName=REDACTED}}"

Have checked on the edge and the alarm is in the events but cleared and acknowledged, have reset the Alarm journal on Edge just in case.

Have set off new instances of said alarms and they come up as new alarms (and clear/acknowledge ok) so I 'm a bit stuck as to how to fix. Anyone else had this happen?

Resolved.

For those who end up here with the same issue, disable, save then re-enable alarming in the tag provider and they clear out.
