Additional when Gutenberg is activated

I have activated Gutenberg via function.php.
When outputting the events and venues, the comments are now enclosed by the Gutenberg blocks with additional <p>.

Original HTML in Editor

<!-- wp:heading {"level":5} -->
<h5>Headline</h5>
<!-- /wp:heading -->

Output in Frontend

<p><!-- wp:heading {"level":5} --></p>
<h5>Headline</h5>
<p><!-- /wp:heading --></p>

Has someone an idea?
Thanks for help
Achim
