I'm not seeing the TaskSubType field for that record in any of the screenshots. I don't believe you have this field on the page layout for the Task object. In the Developer Console, run this query:
SELECT Id, Subject, FORMAT(CreatedDate), TaskSubtype FROM Task WHERE Who.Name = 'Kane Hebrew' LIMIT 50
Then post a screenshot of those results.
