Removing amp amp from page builder when adding iframes

How do we completely remove the code amp amp when adding iframes from the page builder?

Your help would much appreciated. Thanks. 

Hi Tech

 dolphin doesnt really like iframes because they can handle xss vulnerabilities ..

so dont do that ..  you can use

<div style="overflow: auto; width: 400px; height: 300px;">
Enter text here
</div>

which well give you the same effect of the i frames

or if you want to load an external page use

<div><? print file_get_contents('my_page.html') ?></div>

there is a way to do that in java also but i dont remember it

still a lot and lot of ways but dont use iframes
