Idea: Dependency Viewers looks differently in different modules.

Greetings!

I have 2 projects in Idea.
I run Analyze -> Analyze Dependencies in my projects.
The appearance of the results is different:

1) projectA

• somePackage
• < 1.7 >
• Maven: ant:ant:1.6.5
• Maven: com.google.guava:guava:11.0.2
• Maven: com.google.inject.extensions:guice-multibindings:3.0
• Maven: com.google.inject:guice:3.0

2) projectB

default package
          com
               google
                        common
                              base
                                   Objects.class

The controls of Dependency Viewer tab are also different: the one which I like (projectA) has show/hide module button. When I press this button I see the switch from state I like (projectA) to state I dont like (projectB).
But in projectB this button is absent.

Also I cannot select 'Module projectB' while specifying dependency analysis scope.
Also the labels of the modules differ: projectA [projectA] and simply projectB

Whats up?
