If you no longer need a task template, you can delete it on the Task Templates page. Be very careful with deleting task templates. We don't have a way to undo the action, and it can greatly impact your transaction(s) if you delete the wrong one.
Step 1:
Find the task template you want to delete and click on Options. Select Delete from the drop-down.
Step 2:
A pop-up will appear where you can either cancel the action or click on Yes to delete the task template.
IMPORTANT:
Be careful in deleting a Task Template as this cannot be undone and cannot be retrieved.
