Separator / Whitespace Broken on Custom Post Type

I have a custom post type (events) which I had to use this filter to get the Advanced Layout Builder to appear –

add_filter('avf_builder_boxes', 'add_builder_to_posttype');
function add_builder_to_posttype($metabox)
{
	foreach($metabox as &$meta)
	{
		if($meta['id'] == 'avia_builder' || $meta['id'] == 'layout')
		{
			$meta['page'][] = 'event';
		}
	}
	return $metabox;
}

When I add a Whitespace widget on an event I get an error on the front end:

Admin notice for:
Separator / Whitespace

This element was disabled in your theme settings. You can activate it here:
Performance Settings

In the performance settings, setting ‘Disabling of template builder elements’ to ‘Always load all elements’ fixes the problem. Obviously, I’d prefer not to have it set that way. Is there some other filter I can add to put my event post type into the Whitespace’s good graces? :)
