Anchor plus minus sign in non-accordion

When it is not in accordion behaviour and open multiple question opened and closed, anchor plus and minus sign does not behave exactly as it should. following code will fix it.

jQuery(document).ready(function ($) {
    var faqContainer = $(".qafp-faqs"); // <- add
    $("div[id^=qafp-faq]").each(function () {
        var num = this.id.match(/qafp-faq(\d+)/)[1];
        var faq = $("#qafp-faq" + num);
        //var faqContainer = $(".qafp-faqs"); // <- remove
        if (faqContainer.is(".collapsible")) {
            faq.find(".qafp-faq-anchor").bind("click", function () {
                if (faqContainer.is(".accordion")) $(".qafp-faq-answer").not("#qafp-faq" + num + " .qafp-faq-answer").hide();
                if (faqContainer.is(".animation-fade")) faq.find(".qafp-faq-answer").fadeToggle();
                else if (faqContainer.is(".animation-slide")) faq.find(".qafp-faq-answer").slideToggle();
                else faq.find(".qafp-faq-answer").toggle(); if (faqContainer.is(".focus")) {
                    theOffset = $(this).offset();
                    $(window).scrollTop(theOffset.top - 50)
                }
                return false
            });
            $(".expand-all.expand").bind("click", function () {
                $(".expand-all.expand").hide();
                $(".expand-all.collapse").show();
                if (faqContainer.is(".animation-fade")) $(".qafp-faq-answer").fadeIn(400);
                else if (faqContainer.is(".animation-slide")) $(".qafp-faq-answer").slideDown();
                else $(".qafp-faq-answer").show()
            });
            $(".expand-all.collapse").bind("click", function () {
                $(".expand-all.collapse").hide();
                $(".expand-all.expand").show();
                if (faqContainer.is(".animation-fade")) $(".qafp-faq-answer").fadeOut(400);
                else if (faqContainer.is(".animation-slide")) $(".qafp-faq-answer").slideUp();
                else $(".qafp-faq-answer").hide()
            })
        }
    });
    $(".qafp-faq-anchor").click(function () {
        if ($(this).find('.qafp-fa-caret-right').hasClass('qafp-fa-open')) {
            $(this).find('.qafp-fa-caret-right').removeClass('qafp-fa-open');
        } else {
            if (faqContainer.is(".accordion")) // <- add
              $('.qafp-fa-open').removeClass("qafp-fa-open", 1000);
            $(this).find(".qafp-fa-caret-right").addClass("qafp-fa-open", 1000);
            return false;
        }
    });
    $("#qafp_searchform").submit(function () {
        link = $(this).find("#qafp_search_link").val();
        query = $(this).find(".qafp_search").val();
        query = query.split(" ").join("+");
        link = link + query;
        location.href = link;
        return false
    })
});
