[Solved] Added to allowedContent but bullet doesn't work

I added these tags into allowedContent:

  config.allowedContent =
    'h1 h2 h3 h4 h5 h6 p blockquote strong em;' +
    'hr pre code sup sub' +
    'table tr th td caption thead tbody;' +
    'ul ol li dl dd dt' +
    'a[!href,target];' +
    'img[!src,alt,title]';

But the bullet doesn't work, for example:

<ul>

  <li>test 1</li>

<li>test 2</li>

</ul>

If the content is saved and go back to edit again. The bullet tag will be converted to entermode tag. For example:

test 1 <br />

test 2 <br />

If the allowedContent is removed, then it works. Is the issue with ACF?

Thanks
