JavaScript DOM Scripting By Example Editing and Filtering Names States of the Application

What is going on with my application?

Whenever I type in a name, I get the name of the person and the edit and remove button, but I also get an empty editing box with the those same two buttons to the right of each name I type in. I have looked at the code and it looks right. What could be causing this to happen? Here is my code:

const form = document.getElementById('registrar');
const input = form.querySelector('input');
const ul = document.getElementById('invitedList');

function createLI(text) {
  const li = document.createElement('li');
  li.textContent = text;
  const label = document.createElement('label');
  label.textContent = 'Confirmed';
  const checkbox = document.createElement('input');
  checkbox.type = 'checkbox';
  label.appendChild(checkbox);
  li.appendChild(label);
  const editButton = document.createElement('button');
  editButton.textContent = 'edit';
  li.appendChild(editButton);
  const removeButton = document.createElement('button');
  removeButton.textContent = 'remove';
  li.appendChild(removeButton);
  return li;
}

form.addEventListener('submit', (e) => {
  e.preventDefault();
  const text = input.value;
  input.value = '';
  const li = createLI(text);
  ul.appendChild(li);
});

ul.addEventListener('change', (e) => {
  const checkbox = event.target;
  const checked = checkbox.checked;
  const listItem = checkbox.parentNode.parentNode;

  if (checked) {
    listItem.className = 'responded';
  } else {
    listItem.className = '';
  }
});

ul.addEventListener('click', (e) => {
  if (e.target.tagName === 'BUTTON') {
    const li = e.target.parentNode;
    const ul = li.parentNode;
    ul.removeChild(li);
  }
});

I don't see that behavior when I try the code.

But I did notice that all buttons act as "remove" buttons.

Perhaps there are contributing factors in other code parts not shown here. It might be a good idea to make a snapshot of your workspace and share the link to that.

I am using my own text editor, so how would I do that?

You could upload the files into a workspace, or you could post the rest of the source code here.

I posted the rest of my code. I tried it again and it doesn't always do that with all of the names. Sometimes, it is just one name if I select multiple names. I looked at my code again and still can't see what might be causing this problem. I have even checked the developer tools to see it showed any errors and there were none. If you have any ideas what may be causing this problem, I'm all ears. Any help you can offer is greatly appreciated.

Can you give me specific steps to reproduce the issue? I've tried creating up to 5 entries and removing them, but none had any extra buttons.

I would like to show you a screenshot of what I am seeing, but I don't know how to do that.

You can't upload images. If they are hosted somewhere you can link them. But I was hoping you'd tell me what actions to take to create the problem (keystrokes, mouse clicks, etc).

Unfortunately, I am not doing anything different than what he is doing in the video. I even tested his "final" code for this video to see if I get the same results, which I did. It may be something screwy with the browser itself, but I was able to get through the video getting the same result he was with "edit" printing to the console when I clicked on the button. I don't know what is causing it. I guess I will just have to be satisfied that I got through the video and can move on to the next video in this course.

OK, but you might also consider the possibility of a bug in the editor that is simulating the browser for you.

If it looks like this http://prntscr.com/ivizra, then I would suggest re-opening your browser.
