ExportToSpreadsheet adds all "Experiment" fields, not just the selected ones

Using CP 2.1.1 (windows), I finish my pipeline with ExportToSpreadsheet.

I have selected to choose which measurements to export. When I select measurements in the “Image” tree, my output Image.csv file contains only the measurements I selected. However, when I select items in the “Experiment” tree, ALL the experiment lines get added to Experiment.csv. The only thing I want is the Run_Timestamp paramter, but I get 9 extra parameters thrown in (see attached file).
