New sidebar missing from Layout Options -> Select right sidebar dropdown

I am trying to add a new sidebar to my site….which I think I have done, but am having trouble getting it to show as an option on my posts page where, after selecting a layout option with a right side bar, the drop down that lists which right sidebar I can choose from doesn’t list my new side bar.

The side bar has been created to the point that I can add widgets to it. Achieved using this code:

register_sidebar(
		array(
			'name' => 'Sidebar Union',
			'id' => 'sidebar-union',
			'description' => 'This Widget Show the Content in Blog Listing page.',
			'before_widget' => '<div class="widget %2$s">',
			'after_widget' => '</div>',
			'before_title' => '<header class="pix-heading-title"><h2 class="pix-section-title">',
			'after_title' => '</h2></header>'
		)
	);

I cannot find any sidebar.php files to copy. Well, not entirely true…I found one but it was empty and not where any of the previous forumn answers suggested it should be.

I was hoping that this bit of code would do the trick:

() . '/images/head-add.png',
		'advertisement_banner_url' => '#',
		'header_code' => '',
		 'analytics' => '',
		 'responsive' => 'on',
		 'style_rtl' => '',
		 'rtl_switcher' => '',
		 // fotter setting
		 'footer_social_icons' => 'on',
		 'partners_title' => '',
		 'partners_gallery' => '',
		 'twitter_name' => '',
		 'tweets_number' =>'',
		 'trans_switcher' => '',
		 'sidebar' => array( 'sidebar-1','sidebar-home','contact-sidebar', 'sidebar-union'),

which comes from the file theme_activation.php
This is the only place that I can find the 3 other sidebars that show up as options on the new/edit post page under Layout Options -> Select right sidebar.

Theme currently used is KingsClub theme.

I am sure I am missing something really obvious on this one but for the life of me I can’t figure it out and everything that I read on the forums or other says to look for the sidebar.php file. Help PLEASE ??
