When I try to set a featured image - and select: Uploaded to this product - nothing shows. It doesn't show one image. However, we do have images attached to the product which does show in the admin for the same product - under product gallery.
What was tried: deactivated all plugins in the staging area minus WooCommerce, and used the TwentyTwelve theme.
@ldixontv - from WP Engine support ( awesome wordpress hosting ) seems to feel this is a bug in woocommerce.
I am using the latest version of woo commerce and wordpress.
