How to add "Provider VDC" via HTML5 UI of vCloud Director 9.7 ?

Hi,

I have installed vCloud Director 9.7 and i am logging into to new portal using "https://CellIP/provider" url.

I have added vCenter Instance alone without NSX-V. Then I have added NSX-T because of I am using NSX-T on my vSphere Environment.

But, when i look at the provider VDC tab, I can't see any ADD button.( As i understand, this function is not working on new portal yet. )

BUT ! I can't see vCenter Resource when i tried to add Provider VDC via old Flash UI portal. Because, vCenter does not appear because of i added vCenter via HTML5. How can i fix this issue ?
