vApp properties set during OVA deployment are not applied

Describe the bug

I'm deploying a Cisco Expressway appliance from OVA. The ova allows to configure IP, Hostname, NTP, etc settings via vApp Settings. I've tried to set those settings in two different ways, but when I power the VM on, I notice that the settings have not been applied. I tried deploying the VM manually on ESXi, and the settings do get applied.

How do I properly set those settings and have them applied to the guest VM?

Reproduction steps

Running the above code.

Expected behavior

When The VM is powered on, the console should prompt for root and admin password, not the IP settings.
