Do you see that license in your MyVMware portal?
What I could think of - however that's just a guess - is that a Support&Subscription contract exists/existed.
In such a case that is still strange, see https://www.vmware.com/de/support/services/subscription.html
In case the license shows up in your MyVMware portal, I'd suggest that you open a licensing support case regarding this.
