I don’t know why but WP is automatically adding id attributes to h2 tags. I am not supplying any id or class attribute and I don’t need it. Also, it’s adding type="1" to <ol> tag that’s not needed in my case.

You can see it on this page:

Please help, how to stop it?

I need this:

<h2>Meaning</h2>

<h2>Example Sentences</h2>

<h2>Origin</h2>

This is what WP doing with it.

<h2 id="meaning">Meaning</h2>

<h2 id="example-sentences">Example Sentences</h2>

<h2 id="origin">Origin</h2>
