You have installed the latest and greates so youre fine. But your not using the latest and greatest...... you use the older Flash based WebClient when connected to your VCSA. On the VCSA entry page you have 2 choices... please use the HTML5 version and not the old and deprecated Flash one.
When connected directly to the ESXi Hosts with a browser there is only one WebGUI called "Host Client". Its only needed during setup and in term of a disaster. All the other time you work within in vCenter(VCSA).
