Not see *.cpp files in project viewer

Hi guys, I have strange problem - I am not see *.cpp files in Qt Designer project viewer in my project. Others are ok.

I try to clean that, qmake, make... Then I create new solution, first it was ok but after reinstall OS same error on Win 7, Ubuntu and OpenSuse...

Bad project configuration is silly, because I generate new makefile with qmake. I think it can be the newest version of Qt Creator 2.0.1 with 4.7 version Qt. In Qt version 4.6.2 was that OK

Any ideas? :confused:
