OpenKM has many interesting features, but requires some configuration process to show its full potential.
Forum rules: Please, before asking something see the documentation wiki or use the search feature of the forum. And remember we don't have a crystal ball or mental readers, so if you post about an issue tell us which OpenKM are you using and also the browser and operating system version. For more info read How to Report Bugs Effectively.
Did you access this section of the administration a few minutes before starting the OpenKM or the application that started for several hours? because the application take its time to calculate these values -> it is not a real-time calculation, usually it is done 1 time per day ( at midnight )
