Popup Maker & Enfold Menu

Hi,
I am trying to create a popup on the Link in the main menu with Popup Maker, but there are some problems. This is the instruction from Popup Maker: http://docs.wppopupmaker.com/article/51-open-a-popup-from-a-wordpress-nav-menu
It works in a standard template but not with Enfold. Somehow nothing happens when the link is clicked. I’ve tried both versions…
It looks like something is stoping the code in the menu to execute…

Here is what shows up on the page when I add the popmake-421 code to the menu:

<li style="cursor: pointer;" id="menu-item-206" class="popmake-421 menu-item menu-item-type-custom menu-item-object-custom av-menu-button av-menu-button-bordered menu-item-top-level menu-item-top-level-5 pum-trigger current-menu-item">
<a class="pum-trigger" style="height: 88px; line-height: 88px; cursor: pointer;" href="#popmake-421" itemprop="url">
<span class="avia-bullet"></span>
<span class="avia-menu-text">GET DEMO</span>
<span class="avia-menu-fx"><span class="avia-arrow-wrap"><span class="avia-arrow"></span></span></span>
</a></li>

If I add the code to the main content, then it opens normaly

Could you pls let me know, if there is a workarround for Popup Maker in Enfold theme.
Thank you
Ananda
