Windows 10 always installed as Home, and once your Pro license is activated it will install the Pro feature set. I would confirm it's activated. From a command prompt type slmgr /dlv. If it isn't activated or it shows home, try to re-install the license. From the command prompt type slui 3 and re-enter your license. If it still doesn't work you may need to call Microsoft and work with them to get it straightened out. Licensing calls should be free.
