Have you had a similar problem with the installation Windows 10 Pro below?
“Laptop came with Windows 10 Home pre-installed. I upgraded this to Pro using the Microsoft Store.
When doing a clean install it installs Home without prompting, instead of Pro. Is there a way to force it to install Windows 10 Pro on a clean install?”
