Hello,
The linked variations are working based on common attributes, which is causing the other weights to be hidden. To display all variations properly, try setting up the products as individual variations with unique attributes like width and weight, rather than linking them. This way, each variation will display correctly, regardless of inconsistent attributes across products.
You can read more here and configure it.
