Hi,
Please see the field "name" in your variant screenshot.
Like I was telling you in my previous message, you set a name and that is this information which is displayed in the product page.
So, you can leave the field "name" empty in order to retrieve the automatic naming OR you can set manually names for your variants.
Please understand that is a new feature ; it is an improvement because it let you configure what you want to display in the product pages.
