Sorry Lynn, I realized that would change your dates as well. The only option I could find to workaround the wrapping for now is to change the zoom, then you are able to see more of the text in the roadmap item without it overlapping into the next date, but it depends on how long the text is on whether this might help and how much of the roadmap you want to view at one time.
To change the zoom:
1. Click on the settings icon on the right hand side
2. Then you can adjust the zoom on the top of the popup window that appears
