maybe this can help you:
1. Open frontend.js in assets\js directory.
2. In tawcvs_variation_swatches_form function: Sub-function .on( ‘click’, ‘.swatch’, function ( e ) {
Define:
attribute_title = $el.attr('title')
$label = $el.closest('tr').find('.label').first(),
And change this if:
if ( $el.hasClass( 'selected' ) ) {
$select.val( '' );
$el.removeClass( 'selected' );
if ($label) {
$label.html('<label for="pa_color">Color</label>');
}
delete selected[selected.indexOf(attribute_name)];
} else {
if ($label) {
$label.html('<label for="pa_color">Color: '+ attribute_title +'</label>');
}
$el.addClass( 'selected' ).siblings( '.selected' ).removeClass( 'selected' );
$select.val( value );
}
update your server directory .. and test it.
