About Dorico Pro 5 Competitive Crossgrade from Finale

I am Japanese. Please excuse the imperfect English translation.

I tried to purchase 8 licenses of Dorico 5 Pro with 8 licenses of Finale 27 from the following website
https://verify.steinberg.net/92170/start?_gl=1*1k0m8g5*_gcl_au*Njg2NDY0MDMxLjE3MjU3ODc4NTQ.

I selected “8” for the quantity and attached a PDF file with the information for the 8 Finale 27 licenses. (I split the PDF into three files because it only recognizes the first three pages).
I later received a quote, but the quantity was set to 1.

How can I purchase multiple Dorico licenses with multiple Finale licenses?

Sincerely.
