Align layered image to the center of full-width slider

Hi again, I liked the plug in so much, I’ve decided to replace my other plugins.

Currently, I am trying to create a full width slider with a layered image at its center.

On the size panel I’ve entered the slider size as 1200px x 500px, background fill mode to ‘fill’ and responsive to full width.

On the sliders I have placed and image on a layer and centered it.
When previewed on screen sizes 1200px and below, the layered image is centered however this is not so after 1200px.

[ * ] <– 1200px and below

[ * 　　 ] <– 1200px and above

I hope this makes sense to you.
Please advice.

ps. Thanks again for this wonderful plugin!
