Hello,

Sorry for the delay.

Unfortunately, the slider library does not assume hiding the carousel when the page loads.

We can suggest a custom code to solve this issue partially:

(function($) {
	$(document).on('click', '.wd-tabs .wd-nav-tabs > li', function (e) {
		var $slider = $(this).parents('.wd-tabs').find('.wd-slider');

		if ( $slider.length ) {
			setTimeout( function () {
				$slider.flickity('resize');
			}, 150)
		}
	});
	})(jQuery);

Please add the code to the functions.php of the child theme.

If you have any questions please feel free to contact us.

Best Regards
