Hi,

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.

This sounds like a persistence issue.

1. Set the values as non-persistent that you do not want.

1. Save and close the view. Reopen the view, you should see null values.

1. Then you can delete them. Save your view and reload your browser.
