John Mueller from Google explained this to me at Google+.
The main problem here is that these pages all pass through a very similar login page, which makes it really hard for our systems to differentiate. It looks like we have the same problems as other webmasters have :-). Given that the login-URLs are not completely identical, this will likely settle down and fix itself.
