Internet radio. Differences between LMS 7.7.2 and 7.7.3

I have two Logitech Media Servers. v.7.7.2 is running on a old pc and v.7.7.3 is running on a Pogoplug E-02 and is intended to be my low wattage server replacement. The 'Internet Radio' options on the Logitech Media Server <localhost:9000> page are wildly different between 7.7.2 and 7.7.3.

7.7.2 gives the following options:
>Internet Radio
-Staff picks
-Local
-Music
-World
-Search
-Tune In URL

7.7.3 gives the following option:
>Radio
-Tune In URL

I have searched Settings>Plugins for Internet Radio settings to enable. In fact, the 7.7.3 version is missing a plugin called 'Internet Radio (v.1.0) - Internet Radio Directories'.

Does anyone know where the Internet Radio went in my v.7.7.3? Or how I can add the Local, World etc. choices.

Any help is appreciated, it is driving me crazy...
