Как исправить необычное поведение веб-страницы - несколько активных btn из «портфолио»

У меня проблема с исправлением этого необычного поведения веб-страницы. Я включил ссылку на страницу Github. После удаления тега nav проблема решается. Но мне нужен тег nav.

Я попытался удалить элемент nav из консоли dev и обнаружил, что тег nav влияет на следующий раздел "workshop_intro".

Вот ссылка на страницу Github: https://sarang13579.github.io/expt/

Код Github: https://github.com/sarang13579/expt

<section class="workshop_intro">
<div class="container py-2">
  <h1 class="py-4"><strong>Gallery</strong></h1>
  <p>Cut and Engraved products range</p>

  <h2>PORTFOLIO</h2>
  <div id="myBtnContainer">
    <button class="btn active" onclick="filterSelection('all')"> Show all</button>
    <button class="btn" onclick="filterSelection('wood')"> Wood Cutting and Engraving</button>
    <button class="btn" onclick="filterSelection('stone')"> Stone Engraving</button>
    <button class="btn" onclick="filterSelection('glass')"> Glass Engraving</button>
    <button class="btn" onclick="filterSelection('others')"> Others Cutting and Engraving</button>
  </div>

Я ожидаю, что кнопка в разделе портфолио "workshop_intro" будет выделять по одному, не удаляя тег nav.

Возможно, проблема связана с наличием другого элемента HTML с классом «active».запрос document.getElementsByClassName("active"); возвращает элемент li из навигационной панели

<li class="nav-item active"> <a class="nav-link px-5" href="index.html">Home</a> </li>

Для более точного выбора кнопки вы можете использовать document.querySelector(".btn.active");

Ниже приведенрабочий код 

filterSelection("all") // Execute the function and show all columns
function filterSelection(c) {
  var x, i;
  x = document.getElementsByClassName("column");
  if (c == "all") c = "";
  // Add the "show" class (display:block) to the filtered elements, and remove the "show" class from the elements that are not selected
  for (i = 0; i < x.length; i++) {
    w3RemoveClass(x[i], "show");
    if (x[i].className.indexOf(c) > -1) w3AddClass(x[i], "show");
  }
}

// Show filtered elements
function w3AddClass(element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split(" ");
  arr2 = name.split(" ");
  for (i = 0; i < arr2.length; i++) {
    if (arr1.indexOf(arr2[i]) == -1) {
      element.className += " " + arr2[i];
    }
  }
}

// Hide elements that are not selected
function w3RemoveClass(element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split(" ");
  arr2 = name.split(" ");
  for (i = 0; i < arr2.length; i++) {
    while (arr1.indexOf(arr2[i]) > -1) {
      arr1.splice(arr1.indexOf(arr2[i]), 1); 
    }
  }
  element.className = arr1.join(" ");
}

// Add active class to the current button (highlight it)
var btnContainer = document.getElementById("myBtnContainer");
var btns = btnContainer.getElementsByClassName("btn");
for (var i = 0; i < btns.length; i++) {
  btns[i].addEventListener("click", function(){
    var current = document.querySelector(".btn.active");
 current.classList.remove("active");
    this.classList.add("active");
  });
}
