Old jQuery version is being enqueued from Google CDN

I am having an number of issues with Enfold 3.8 and Formidable Pro. One issues is that there is an old version of jQuery being enqueued in the following files:
enfold > config-layerslider > LayerSlider_old > wp > scripts.php line 18 & 80
enfold > config-layerslider > LayerSlider > wp > scripts.php line 20 & 81
// Use Gogole CDN version of jQuery

if(get_option('ls_use_custom_jquery', false)) {
	wp_deregister_script('jquery');
	wp_enqueue_script('jquery', '//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js', array(), '1.8.3');
}

enfold > framework > php > avia_shortcodes > av_prev.php line 26

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js" ></script>

It seems that it’s the layerslider that is hijacking the jquery. Is there a reason for such an old version of jquery?
