Select duplicate in filter

Hi, Hope you can help…
Since the last update, sometimes the filter select field in the form is duplicated,
just sometimes, specially when you use an incognito browser.

Example:
https://debrisfreeoceans.org/responsible-products
<div id=”filter-category”>
<select id=”pods-form-ui-filter-product-category” name=”filter_product_category” class=””><option value=”26″>Bag</option><option value=”1″>Bowl</option><option value=”2″>Coffee Lid</option><option value=”3″>Coffee Sleeve</option><option value=”4″>Cup</option><option value=”5″>Cutlery</option><option value=”6″>Plate</option><option value=”25″>Stirrer</option><option value=”7″>Straw</option><option value=”8″>Straw + Spoon</option><option value=”9″>Tableware</option><option value=”10″>Takeaway</option><option value=”11″>Takeaway Lid</option><option value=”14″>Water</option></select>

<select id=”pods-form-ui-filter-product-category” name=”filter_product_category” class=””><option value=”26″>Bag</option><option value=”1″>Bowl</option><option value=”2″>Coffee Lid</option><option value=”3″>Coffee Sleeve</option><option value=”4″>Cup</option><option value=”5″>Cutlery</option><option value=”6″>Plate</option><option value=”25″>Stirrer</option><option value=”7″>Straw</option><option value=”8″>Straw + Spoon</option><option value=”9″>Tableware</option><option value=”10″>Takeaway</option><option value=”11″>Takeaway Lid</option><option value=”14″>Water</option></select>
</div>

and this is php code we use:
`//init ALL compostables
$params = array(‘where’ => “t.visible = ‘1’”,’limit’ => ‘-1’);
$compostables = pods( ‘Compostable’ , $params);
echo ‘<div id=”to-clone-filters-compostables”>’;
echo $compostables->filters( array(‘fields’ => array( ‘product_category’, ‘size’)) );
echo ‘</div>’;
echo ‘<div id=”filter-category”>’;
echo ‘</div>’;

Thanks
