Flex Active slide does not display while using shortcode

I have tried to list multiple products using the [product page id=”] shortcode.
For some of the products the featured image is collapsed, and you have to either refresh the page or click on another gallery image for it to expand.

Basic code on page

<p><a id="bracelet"></a>[product_page id="7848"]</p>
<hr />
<p><br />
<a id="amplifier"></a> [product_page id="7847"]</p>
<hr />
<p><br />
<a id="harmonizer"></a> [product_page id="7849"]</p>
<hr />
<p><br />
<a id="sol"></a> [product_page id="7850"]</p>
