Shortcode instead of Custom Widget

Hello,

i’ve an issue with shortcodes being displayed instead of custom widgets like this:

[siteorigin_widget class="Neo_Teaser"][/siteorigin_widget]

I’m running an up to date WordPress with Page Builder by SiteOrigin and SiteOrigin Widgets Bundle. The Widget folders are extended by this Filter:

add_filter('siteorigin_widgets_widget_folders', function($folders) {
    $folders[] = get_template_directory().'/widgets/';
    return $folders;
});

Even if i just implement a simple widget with the guide under https://siteorigin.com/docs/widgets-bundle/getting-started/creating-a-widget/ the same issue happens.

Thanks for any input.

Regards,
Christian
