Hi there,
I’m not sure of the question here – would you mind elaborating a bit more on what exactly you’re looking for help with?
As a sidenote, I’ve just tested thing on my local testing installation and the entire variable product was duplicated. Here’s a screenshot of what that looks like on my side:

If you’re seeing something different it likely means that there might a conflict coming from one of your plugins or the theme you’re using. If that’s the case here, please share a copy of your system status report as found under **WooCommerce > System Status**.
Thanks!

We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
