Default [Q] Need help restricting text length, Margins in Rich Text aren't working

Firstly, I *love* ZWP and have been using it religiously.

With my new Nexus 5, however, I decided to make a new widget to match the current phone instead of my previous setup. I like having my next 3-4 calendar appointments shown in a list with dates and times and the heading, in the #C0SEEE dd - HH:mm# #C0TITLE# format. Some appointments though have longer titles and interfere with other items I have entered into the widget.

I tried using the new Rich Text feature and setting margins to various lengths and setting lines to 1, but a long appointment title still bleeds over into the next portion of my layout.

What am I missing?
