Opening 6.0.x web project in Selena?

When I open a project with one web module created in 6.0.x in Selena (both M1 and build 6913, something strange happend with my "Modules and Library to package".
All my libs are duplicated; it shows first all my "libs" in black but with status "Do not package". and the all my "libs" are listed again, but this time in red but with status "Copy files to"
(see attachment)

Is this a known bug or am I missing something?


Regards,
