Alarm acknowledge sometimes useless

Ignition Vision 8.1.2
In Alarm Status Table , some alarms click acknowledge button, uesless, always show in table.

How to resolve it?

The first step should be to upgrade. There are some issues with alarm acknowledgement solved in later Ignition versions.

Is this Ignition Release Notes in Version 8.1.15
like this tip:

Our system is already in use ,can't update the sofeware immediately。
Is there any other way to solve the proble?

No. If it is indeed that bug, which I consider likely, then it is a bug in the software. There's no workaround besides updating the software to a version where the bug is fixed.
