Hello,

We just visited your website but didn’t see any of the mentioned problems. Part of your variations is in stock so the other ones are simply set to be out of stock or doesn’t have count number of in-stock items.

You can upload your image for each variation while editing it in Dashboard. See the place to upload your image on this screenshot https://xtemos.nyc3.digitaloceanspaces.com/wp-content/uploads/2018/02/Screen-Shot-2018-02-11-at-6.46.10-PM.png
