I have this issue whereby I create a block with HTML code but the frontend is displaying the html instead of just the display text?

Any ideas what I’m doing wrong? In the frontend code its showing as the following

<pre><code><h1>Week 1</h1>
    <p>Praesent quis velit tincidunt, vulputate mauris semper, volutpat velit.
            Quisque finibus est in condimentum maximus. Sed sed luctus urna.
            Suspendisse semper elit id venenatis accumsan.
            Proin purus arcu, dignissim eget euismod in, dictum quis felis.
            Aliquam pretium risus vel erat suscipit, vitae hendrerit neque ullamcorper. </p>
</code></pre>

Instead of the following behind the scenes

<h1>Week 1</h1>
<p>Praesent quis velit tincidunt, vulputate mauris semper, volutpat velit.
Quisque finibus est in condimentum maximus. Sed sed luctus urna.
Suspendisse semper elit id venenatis accumsan.
Proin purus arcu, dignissim eget euismod in, dictum quis felis.
Aliquam pretium risus vel erat suscipit, vitae hendrerit neque ullamcorper. </p>

Any help would be great, thanks
