When I compare the "Releases" page in Portfolio to the "Releases" page in my project, the status of the project is not the same. E.g. in my project the status is 4/5 tasks are green/ done, yet in Portfolio the same release is marked as empty / white/ not a single task is done.
Other project releases are displayed correctly in our Portfolio, though.
I cannot find a difference between projects that do and that don´t display correctly in Portfolio.
