Tips: How do I delete a comment (Decision detail)?

Problem:

I am creating a diagram. I entered a comment at the bottom of a Decision detail. How do I delete it? The only option I see is to delete the particular Decision and re-build a duplicate of it. 

Solution from Support:

Thanks for posting a question. Yes that is correct, you would need to delete the Decision and re-build a duplicate. If it's a lot to rebuild your decision please email support and we can delete it for you in the database. It's an omission in the current UI that we are working to address.
