I am seeing that my standard calculated attributes are showing up as null. Zendesk support said this to me:
"At this time, unfortunately what you are experiencing is expected."
Below is the formula that shows up as null for many, but not all tickets:
IF (
[Updater role]="End-user"
AND [Comment present]=TRUE
AND [Comment public]=TRUE
AND DATE_LAST_FIX([Update - Timestamp],[Comment present],[Comment public],[Updater name],[Updater role])=[Update - Timestamp])
THEN [Update - Timestamp]ENDIF
