When changing the number of shelving times in the Alarm Status Table in Ignition Perspective the component adds an additional time of one of the existing ones.
In this case I removed the first time which was 30 minutes (value of 1800). That way I only have 5 shelving times.
But when I run this in the browser I see that “4 hours” are added in the bottom of the list so I have a total of 6 times again.
If I save the view with only 5 shelving times and close it and open it again in the designer I also see that a sixth time is being added.
