Clockwise will recognize certain keywords to inform whether Lunch should be synced that day. If you have a meeting on your calendar with words "Lunch" in it, Clockwise will assume you manually scheduled your lunch block and will not create a duplicate hold.
If you're confused as to why a lunch event was not created, scan your calendar to see if an event may be considered a lunch meeting. If you'd like your Lunch event to persist, consider renaming the meeting.
