Please replace this code section:

<script type="text/javascript">
let isScroll = false;
window.onscroll = () => isScroll = true;
setInterval(() => {
        if ( isScroll ) {
            isScroll = false;
           document.getElementById('headeradd').style.display = 'none'
           document.getElementById('contenedorMenuSuperior').style.cssText = "top: 0px !important"
           }
    }, 5000);
</script> 

to this:

<script type="text/javascript">
window.addEventListener('wheel', function(evt) {
        if(window.scrollY >= 100) {
         setTimeout(function(){
         document.getElementById('headeradd').style.display = 'none';
         document.getElementById('contenedorMenuSuperior').style.cssText = "top: 0px !important";
       }, 5000);
     }
   });
</script>
