Export exports whole website?

Hi there,

I have a strange thing happening when using the export function (add to calendar).

Somehow the event description includes the whole frontpage content?

…

</summary><description><text>
<link rel="preload" href="http://.../wp-content/themes/themify-ultra/themify/themify-builder/css/themify-builder-style.css?ver=4.8.8" as="style" /><script type="text/javascript">
				if(document.getElementById( "themify-builder-style" )===null ){
					var el =  document.getElementById( "builder-styles-css" );
					if(el!==null){
					var link = document.createElement("link");
					link.id="themify-builder-style";
					link.rel="stylesheet";
					link.type="text/css";
					link.href=el.getAttribute("data-href");
					el.parentNode.replaceChild( link, el);
					}
				}
			</script><div id="themify_builder_content-8" data-postid="8" class="themify_builder_content themify_builder_content-8 themify_builder">
    	<!-- module_row -->
	<div   class="themify_builder_row module_row clearfix fullcover fullwidth_row_container module_row_0 themify_builder_8_row module_row_8-0 tb_be9ac65">
	    	    <div class="row_inner col_align_top" >
			<div  class="module_column tb-column col-full first tb_8_column module_column_0 module_column_8-0-0 tb_3253d60 repeat" >
	    	    	        <div class="tb-column-inner">
		    <!-- module text -->
<div  class="module module-text tb_4008c2b  repeat  ">
            <div  class="tb_text_wrap">

…

How can I prevent this and only export the event description?

Also, the Maps API does not work, because it requires billing. Is there a solution besides not using maps or paying?

Kind regards
