Error in Alarm DisplayPath Expression

When configuring an expression for Alarm DisplayPath, if first attempth to create an expression in invalid, one have to delete and re-create the alarm to make the fixed expression work. (Ignition 8.1.7).

Anyone else seen this?

Can you describe in more detail or provide a screen recording? If I add an invalid expression to display path, I’m still able to go back ‘into’ it to customize it further.
