content filter (slider) - collapsed

Hello,

i have a filter (slider mode) , if i click to buton, then everything works,  and slider shows all fillters. Like in picture.

But after refresh or if i set one filter (with auto GO button = autoconfirmation filter) , page is refreshed and slider is ALLWAYS COLLAPSED.
This should work like this ? Or can stay not colapsed, if refreshed or set filter ?
Any chance to change it : if i set the filter or refresh it when slider is open, slider stay open " NOT COLLAPSED " ?

I have: <div id="fcfilter_form_slider_cat_mcats_filters_slide" class="accordion-collapse collapse " aria-labelledby="fcfilter_form_slider_cat_mcats_filters_slide-heading" role="tabpanel">
I need have : <div id="fcfilter_form_slider_cat_mcats_filters_slide" class="accordion-collapse collapse show" aria-labelledby="fcfilter_form_slider_cat_mcats_filters_slide-heading" role="tabpanel"> when set a filter and refreshed ..

Maybe some template conflict:
last version of Flexicontent + Helix Ultimate 

bootstrap.php:
 public static function addSlide($selector, $text, $id, $class = ''): string
    {
        $in        = static::$loaded[__CLASS__ . '::startAccordion'][$selector] === $id ? ' show' : '';
        $collapsed = static::$loaded[__CLASS__ . '::startAccordion'][$selector] === $id ? '' : ' collapsed';
        $parent    = static::$loaded[__CLASS__ . '::startAccordion'][$selector] ?
            'data-bs-parent="' . static::$loaded[__CLASS__ . '::startAccordion'][$selector] . '"' : '';
        $class        = (!empty($class)) ? ' ' . $class : '';
        $ariaExpanded = $in === 'show';
        return <<<HTMLSTR
<div class="accordion-item $class">
  <h2 class="accordion-header" id="$id-heading">
    <button class="accordion-button $collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#$id" aria-expanded="$ariaExpanded" aria-controls="$id" role="tab">
        $text
    </button>
  </h2>
  <div id="$id" class="accordion-collapse collapse $in" aria-labelledby="$id-heading" $parent role="tabpanel">
    <div class="accordion-body">
HTMLSTR;
    }
