Hey Stephen

Thank you for posting in the Lucid Community! I think I understand the issue you are experiencing and I have included a short video below that I think should help us out. You have a couple of options: You can drag a new Decision shape out and start over as "Yes" lines should be the first ones OR you could change the text on the line that says "no" to a "yes." 

Hope this helps--if this isn't quite what you were looking for please reach back out on this thread with a screenshot of what you are seeing with a short description of the issue you are experiencing. Cheers!
