Issue with parent and child listings

Hello everyone. My products are already at Amazon warehouse facility which means they already have ASINs attached on the packaging. My problem is parent and child listings are not connected. I opened 10 cases with support but they are so useless I don’t even know if they ever helped anyone. Guys, how to solve this issue? I created new parent listings and added color variations to them. Now on the website , when I click on parent listing , it has black color product on the picture , color in description is green🤨, (I cannot change it anywhere!!) , and no child options for customers to click and select 🤯 I feel so desperate at this point … I would appreciate your help if you ever experienced the same issue.

The pic is below (sorry for the quality)

This is a child variation

Are the listings active, even though they are not connected?
