CCS4 Graphing in HVPM Sensorless Example

I am working with the HVPM Sensorless example in control suite using the 28335 EZDSP and my own inverter hardware.  I am trying to look at various signals in the Dual Time graph.  It is not working.  Whne I follow the example in the documentation using start adress A= DLOG_4CH_buff1 and start address B= DLOG_4CH_buff2, I get signals that look like the signals in the documentation.  When I try to view other signals such as start adress A =  svgen_dq1.Ta and start address B = svgen_dq1.Tb, I get a DC line at zero for each graph.   What am I doing wrong?

Thanks,
