Edit Result Columns fancy box cancel button does not reinitialize values

1. On a Content View list view screen, click the Edit Results Columns icon.

Expected Result: The Edit Results Column screen will reflect what is currently displayed on the Content View's list view screen so that the user can adjust as needed.

Actual Result: The Edit Results Column screen still displays the changes that user made for Step 2 but never applied. These changes should not be retained since the user clicked Cancel or clicked the X to close without saving. The selection displayed should match the Content View's actual state.
