Can't White Label with Pro account

A big part of the reason I upgraded was to be able to white label to my clients.
I was able to do this with the first website for the editor and for the billing & it is still good.
But for my other site, I set it up and it was good until I tried to send out the billing. once I did that it’s telling me I need pro account to white label & I have the pro account. Now for the second website only, it doesn’t give me the option to white label anymore.
Please help me resolve this
