The proxy GUI is not looking like the expected Proxy GUI but instead is defaulting to the SKY UI.

Proxy Advanced UI

The default UI can be changed from the SKY UI to the Proxy Advanced UI via the following command line interface commands.
proxy#configure terminal
proxy#(config)ui
Proxy#(config ui)default advanced
ok
To only temporarily browse the Advanced UI instead, click on 'Advanced Configuration'. A new browser tab opens up with the Proxy Advanced UI
