Parent Asin Listing shows only one Child Asin

Hi everyone. Just a quick question, which I couldn’t find the answer in any forums.

I created my first FBA listing, for my product which has 6 colours. So I adjusted my listing with 6 colour variation and I created the shipment for FBA. I am about to send the shipment in 2 days to Amazon warehouse.

But now, when I checked my listing, I see that the parent asin listing (in Manage Inventory page) reaches only one child listing (the first one from the Manage FBA inventory page).

So, I would like to ask, isn’t it suppose to show all 6 colours combination listing? or is it because I still have no active or fulfillable inventory yet? Are they gonna be merged automatically when my FBA inventory will be active? If not, where did I made mistake, and how I can merge 6 colours together?

Thank you for your answers in advance.
