Conflict with WooCommerce Wishlists (spinning icon)

Hi!

After the last updates I get no feedback after submit except the spinning icon. As mentioned in the FAQ, I searched for a conflict with a plugin or the teme.

It always happens when the WooCommerce Wishlists plugin is activated, even when only CF7, WooCommerce and the Wishlists plugin are activated.

After chatting with the WooCommerce support, they said that they will pass this to the team, but that they don’t expect that this will be fixed by them, but has to be fixed by CF7.

In the HTML code I only found the following differences (with Wishlists plugin activated):

<link rel='stylesheet' id='woocommerce-wishlists-css'  href='https://mysite/wp-content/plugins/woocommerce-wishlists/assets/css/woocommerce-wishlists.css?ver=4.9.6' type='text/css' media='all' />

<script type='text/javascript'>
/* <![CDATA[ */
var wishlist_params = {"root_url":"https:\/\/mysite","current_url":"\/kontaktformular\/","are_you_sure":"Sind Sie sicher?","quantity_prompt":"How Many Would You Like to Add?"};
/* ]]> */
</script>
<script type='text/javascript' src='https://mysite/wp-content/plugins/woocommerce-wishlists/assets/js/woocommerce-wishlists.js?ver=4.9.6'></script>
<script type='text/javascript' src='https://mysite/wp-content/plugins/woocommerce-wishlists/assets/js/bootstrap-modal.js?ver=4.9.6'></script>

<div id="wl-list-pop-wrap" style="display:none;"></div><!-- /wl-list-pop-wrap -->
<div class="wl-list-pop woocommerce" style="display:none;">
    <!--<a class="wl-pop-head">Add to Wishlist</a>-->
    <dl>
				
				
				            <dt><strong>My Wishlists:</strong></dt>
			                <dd>
                    <a class="wl-add-to-single" href="#" data-listid="46495">My Wishlist</a>
                </dd>
					    </dl>
			<strong><a rel="nofollow" class="wl-add-to-single button" data-listid="session" href="#">Create Wishlist</a></strong>
	</div>

Is it possible to fix this on your side? Thank you very much.

PS: The embedded bootstrap-modal.js is version 2.2.1.
