I'm currently using the Rich Text editor in my grid layout for content.

When I edit the code and place a <h1>Harrisburg Wedding and Portrait Photographer</h1> tag hit submit and then save my page it converts my h1 to a p. also in the code editor i've added classes for gtm tag triggers, but yet again when i hit save the class attribute is dropped.

<h2 class="headerprice">Pricing and Information</h2> on save becomes <h2>Pricing and Information</h2>

here is my mce config....
