WooCommerce Product Variations Swatches

I wanting to buy this plugin but when I added the swatches it does not show a clean UI. Can you help to check what is going on and can you please help me to fix it please ?

I have added the website link on the private section. For you to take a deeper look.

I want to make it look like the picture I have attached for you. It was advertised as part of your plugin.

Thanks
