HTML Embed Code changes, how to make it remain the same

HTML Embed Code changes, how to make it remain the same

Hi there, 

I am embedding a video from Vimeo into a dashboard. 

The following code is taken from Vimeo using the embed feature: 

<div style="position: relative; padding-top: 56.25%;"> <iframe src="https://player.vimeo.com/video/869556664?h=0737c03545&amp;badge=0&amp;autopause=0&amp;player_id=0&amp;app_id=58479" frameborder="0" allow="autoplay; fullscreen; picture-in-picture" style="position: absolute; top: 0; left: 0; width: 100%; height: 100%;" title="BAE Our People - Cyber (Main Film)" ></iframe> </div> <script src="https://player.vimeo.com/api/player.js"></script>

This looks like the first attached screenshot. 

However, the code then changes without my input to this: 

<div style="padding: 56.25% 0 0 0">
<iframe
      title="BAE Our People - Cyber (Main Film)" style="top: 0; left: 0; width: 100%; height: 100%" src="https://player.vimeo.com/video/869556664?h=0737c03545&amp;badge=0&amp;autopause=0&amp;player_id=0&amp;app_id=58479" sandbox="allow-popups allow-forms allow-scripts allow-same-origin">
</iframe>
<br>
</div>

Making the video look like the second screenshot.

Is there a way to stop analytics doing this, or write the HTML correctly? 

Many thanks
