The best ux alternative in designing variant of a product on dashboard

I was wondering what would be the best way to display variant when a user clicks on "Add Variant". I already designed two alternatives: display it in ascending order or descending order. I have tested it to internal stakeholders but I still hesitate because the results are 50:50, either they chose Alternative-A or Alternative-B.

On Alternative A, when a user clicks "add variant" then it will appear in ascending order. After the user filled the product variant name, the variant 1 will be automatically changed based on the product variant name, so on. The latest variant will be placed on the bottom. Example:

variant 1

variant 2

variant 3 [this is the latest]

Alternative A:

On Alternative B, when a user clicks "add variant" then it will appear in descending order. After the user filled the product variant name, the variant 1 will be automatically changed based on the product variant name, so on. But, the latest variant will be placed on top. Example:

variant 3 [this is the latest]

variant 2

variant 1

Alternative B:

I would be glad if someone could give me an opinion and a strong justification to which best UX alternative from those two options. On the other hand, I would like to put an indicator state to the latest variant but I still have no idea how to present it. Maybe you could offer me an idea regarding the indicator state. Thank you in advance!
