Bitrix adds display: none; how to fix?

Question

HTML

I inserted the code into the product card in Bitrix through the editor, it adds display: none to all elements;
Although everything is fine when viewing the code.
How to put the code below in Bitrix?

<script src="/css/calc-lef-200/calc.js"></script>
<link rel="stylesheet" href="/css/calc-lef-200/calc.css"/>
<div class="whiteBlock bg-gradient" id="calcform">
