I purchased a license but I'm still a basic user and I can't assign licence

I purchased a license, but my user seems to be still a basic user.

When I try to assign the licence, the page shows me:

"You still have licenses available for users. Assign license to users or manage their license count."

But also:

"You have exceeded the license allocation limit for your account"

So I can't assign the licence to a user, I don't know what to do. 😞
