Vbulletin.org Sub menus are gone?

[VCINet]

Ok I know it has been 2 years since I used Vbulletin, so maybe I have missed a lot.

What I cannot figure out though is why I cannot see the Sub Menus.

When I go to Mods then click on Vbulletin 3.6 Add-ons I cannot see the old menu system like this...

Administrative and Maintenance Tools
Board Optimization
End-User Options
Forum Home Enhancements
Major Additions

etc, etc

The weird thing is when I go into Vbulletin 3.6 Add-ons and copen a thread it shows the sub directory in the heading like this

vBulletin.org Forum / vBulletin Modifications / vBulletin 3.6 Modifications / vBulletin 3.6 Add-ons / Show Thread Enhancements

Can someone explain to me what I am missing here? I have gone through all the CP user options and cannot find any setting to change this.

Thanks
