Bugs in content types

Hi,

I have an issue with embed content on Moodle. I created an activity "Course presentation" on my course page an I used the embed code to embed it directly in my course page. In each page, I have 2 embed Course Presentation. But sometimes, not all time, when I load the page, I have a grey rectangle just below the embed activity :

I don't how I can resolve this problem. Here, you can find my embed code :

<p><iframe src="https://mymoodle.fr/mod/hvp/embed.php?id=268" width="100%" height="910" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p>
<script src="https://mymoodle.fr/mod/hvp/library/js/h5p-resizer.js" type="text/javascript"></script>

I'm in Moodle 3.6.10 and H5P is in 1.21.0 version. I using Chrome but the problem appears on Edge too.

Thank you for your help !

Regards,
