Chemstation Not Properly Identifying Peaks

Hi all! I'm using Enhanced ChemStation, MSD ChemStation E.02.02.1431 for analysis of some GC/MS residual solvent data.

 

It is having difficulties picking up calibrated peaks on the quantitation report.

 

As an example, ethanol has a RT of 2.029min and produced a good calibration curve.  In a sample, obvious ethanol (MS spectrum confirmed) came in at 2.027min.  It integrates when you click on the integrate button, but does not show this peak on the quantitation report.  It just says N.D. for ethanol.

 

Any ideas what may be causing this?
