If you find that 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.
Find the task template you want to delete and click on Options. Select Delete from the drop down.
A pop-up will appear where you can either cancel the action or click on Yes to delete the task template. Again, this cannot be undone so please be careful.
