Question:
When a Task is deleted through XOG the Task ID has a prefix ~dtp. Why?
Answer:
When the task is deleted via XOG or deleted in OWB or MSP the Task ID will have the prefix ~dtp. 
When the task is deleted in the UI the Task ID won't have the prefix ~dtp. 
That is by design and the reason is to distinguish how the task was deleted.
