Phil, I can always count on you for candor.
"You've apparently broken that expectation by putting the alarm name in the display path and leaving the alarm name the generic "Alarm""
Incorrect. The DISPLAY PATH is showing the alarm detail (the nature of the alarm, such as "Hi", "Lo", "Failed to start", etc). The NAME and LABEL columns have "Alarm" in them.
The fix is shown in the attached images. Linking LABEL to the {itemName} gives you the Ignition tag name without all the rest of the path info.
