Repeat the same word over and over in menu

I have a menu with a list of a lot of management and configuration GUIs. They are listed below a headline of the category. Like so:

Managemanet

Xxxxxx Management

Xxxx Management

Xxxxxxxx Management

Xxxxx Management

Xxxxxxxxxx Management

Configuration

Xxxxxxxxx Configuration

Xxxx Configuration

Xxxxxx Configuration

Xxxxx Configuration

Xxxxxxxx Configuration

My question is: Do I have to repeat each word in the menu or is it enough to let the headline do that job?

When the user clicks on a link he will go to that GUI and see the headline, which will be the full name, i.e. Xxxxxxxx Configuration (not just Xxxxxxxx). Do you think the non-consistency will cause confusion?
