Clash between this plugin and function : siteorigin_panels_prebuilt_layouts

Hi I have the following code, which generates a template:

function mydtheme_prebuilt_layouts($layouts){
    $json = '{"widgets":[{"title":"","panels_info":{"class":"WP_Widget_Calendar","raw":true,"grid":0,"cell":1,"id":0}},{"title":"","panels_info":{"class":"WP_Widget_Categories","raw":true,"grid":1,"cell":0,"id":1}}],"grids":[{"cells":2,"style":{}},{"cells":2,"style":{}}],"grid_cells":[{"grid":0,"weight":0.5},{"grid":0,"weight":0.5},{"grid":1,"weight":0.5},{"grid":1,"weight":0.5}]}';

    $obj = json_decode($json);
    $layouts['home-page'] = array(
        // We'll add a title field
        'name' => __('Home', 'sz'),    // Required
        'description' => __('Home', 'sz'),    // Optional
        'widgets' => $obj->widgets,
        'grids' => $obj->grids,
        'grid_cells' => $obj->grid_cells
    );
    return $layouts;

}
add_filter('siteorigin_panels_prebuilt_layouts','mydtheme_prebuilt_layouts');

The problem is that if I disable the plugin: ‘SiteOrigin Widgets Bundle’ work load ‘layout’, when I select an item defined within the ‘page builder’ and if you stay active by loading the layout and never shows it. regards
