PCDmanager Liquid Density Data Fitting

Having a problem fitting external data for liquid density for use in PCDmanager for Compound W.
Ideal gas heat capacity
  • selected estimating method from available choices in <T Correlations> panel
    imported data
    fit imported data
Seems to have worked, but regression statics are unverified by me at this time.

Liquid density
  • no estimating choices presented in <T Correlations> panel
    imported data
    no curve to see to fit data to
Imported data is shown in the <Data> panel.
Dialog <Use table values to fit new data?> ==> Yes
Regression statistics are displayed in <Key....Value> pane of <T Correlations> panel
<Table> and <Plot> panels are empty
No data in Table and no curve in Plot

How can you fit what you cannot see? Now what? What has happened? Could this be part of the same problem described in my first posting--NO plot?
