Brand approval – something wierd

So I was going to apply for brand approval in 3 amazon markets. I checked all 3 when I went to create a product and it said brand authorisation required. Yet if I entered a different name that I knew was taken it said I had to get catalog authorization etc.

So i submitted for brand approval for all 3 markets. First one came back approved. The other two said it was taken. Which was crazy because if it was how would I have been able to register in all 3 as the option? It would have said already used on product listing page.

I messaged amazon support. Same generic responses blah blah its taken. Copy and paste stuff.

Can someone tell me then why this happened? I was told I had to apply on all different amazon markets but it legit seems that I am authorized to sell that brand because its not coming up with catalog auth either, only GTIN exception error.
