AutoCAD Civil 3D :: Figure Prefix Database And Break Lines

I am running Autocad Civil 3D 2012. I created a figure prefix database that our surveyors were familiar when coding in the field. It is a numeric code list. I received a survey last week that had 6 break lines coded in the point file. Only one of the 6 acts as a break line.

All break lines start and stop with the right line work commands but they fail to break crossing triangle legs. I've checked everything I can think of and the setup looks correct . The only difference between the one break line that works and the others is that break line has sequential point numbers while the other break line codes are scattered throughout the point file.
