If you have dragged the incorrect population into one of the boxes, simply select it and hit the delete key to remove it from the box. Or, you can drag and drop the correct population onto the box, replacing the existing one. You can know what population is in a box by selecting that box (clicking on it); the name of the population that you dragged into the box will be shown in the lower left corner of the window.

Note that some FACS machines collect a fluorescence parameter in the SSC-W channel. This channel will therefore be displayed in the compensation dialog window when sample files in the workspace contain this parameter.
