Isotope – filtered images – how to only show the filtered images in lightbox

I am building a WordPress website. I am implementing isotope for image layout and filtering (isotope.metafizzy) with lightbox plus.
Isotope works great but even if I filtered image category lightbox sow all images, not only those wich belong to the filtered category.

Here is my Js script:

jQuery(function ($) {
var $container = $('#isotope-list');
$container.isotope({
		itemSelector : '.post-item',
  		layoutMode : 'masonry',
	});
	var $optionSets = $('#filters'),
	$optionLinks = $optionSets.find('a');

	$optionLinks.click(function(){
	var $this = $(this);
	// don't proceed if already selected
	if ( $this.hasClass('selected') ) {
	  return false;
	}
	var $optionSet = $this.parents('#filters');
	$optionSets.find('.selected').removeClass('selected');
	$this.addClass('selected');

	//When an item is clicked, sort the items.
	 var selector = $(this).attr('data-filter');
	$container.isotope({ filter: selector });

	return false;
	});
});

I use a child theme I made from the theme Adamos.
I saw that’s a recurent issue with isotope and lightboxes.
I searched all day and I not found a solution… 🙁
Any help is greatly appreciated.
Many Thanks !
