NatTable - CheckBoxCellEditor & CheckBoxPainter displaying the text on single click

I am using CheckBoxCellEditor and CheckBoxPainter to display Boolean attribute inside the NatTable as shown below

Problem : On single click of cell using mouse, it displays boolean value as text as shown below, instead of resetting the state to false.

Below is my code snippet,

//register the column
ColumnOverrideLabelAccumulator columnLabelAccumulator = new ColumnOverrideLabelAccumulator(
                bodyLayer.getBodyDataLayer());
        bodyLayer.getBodyDataLayer().setConfigLabelAccumulator(columnLabelAccumulator);
        columnLabelAccumulator.registerColumnOverrides(0, COLUMN_BOOKMARK_LABEL);

//added the CheckBoxCellEditor and CheckBoxCellPainter to configuration.
     natTable.addConfiguration(new AbstractRegistryConfiguration() {
                    @Override
                    public void configureRegistry(IConfigRegistry configRegistry) {
                        configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, new CheckBoxCellEditor(), DisplayMode.NORMAL,
                                COLUMN_BOOKMARK_LABEL);

                        configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new CheckBoxPainter(ImageUtil.getImage("Images.BookmarkChecked"),
                                ImageUtil.getImage("Images.BookmarkUnchecked")),
                                DisplayMode.NORMAL, COLUMN_BOOKMARK_LABEL);

                        configRegistry.registerConfigAttribute(CellConfigAttributes.DISPLAY_CONVERTER,
                                new DefaultBooleanDisplayConverter(), DisplayMode.NORMAL, COLUMN_BOOKMARK_LABEL);
                    }
                });

I also, have rowselectionProvider to set the default selection to first row and also to refresh the properties UI based on the row selection.

Any pointers on what is the missing link.TIA
