Why doesn't pdomenu navigate on left mouse click?

Question

MODX

I inserted pdomenu into modx, the menu hierarchy on the site has changed, but the transition to another page is not carried out by the left mouse click. Only through the wheel. If you examine the element, then when you left-click on the menu item, an error appears. Tell me why the transition is not carried out?

<nav class="section-header-nav">

</nav>
