mixitup-filter.js

        // Setup MixItUp for card filtering
        var mixer = mixitup('.program-card-container');

        if ($('.program-card-container')) {
					var container = $('.program-card-container')
					var mixer = mixitup(container, {
						callbacks: {
			        onMixStart: function(state, futureState) {
			        },
							onMixEnd: function() {
								container
									.find('.card:visible:first')
									.focus();
							}
				    }
					});
					if (location.hash) {
						var hash = location.hash.replace('#', '.')
						var oldBtn = $('button.selected');
						var newBtn = $("button").find("[data-filter='" + hash + "']");
						mixer.filter(hash)
						oldBtn.removeClass('selected');
						newBtn.addClass('selected');
					}

Same. Found this after so many hours of trial and error.
