Dashboard report inconsistencies

Why is my dashboard report displaying 0 for Average visit duration and Bounced visits and no value at all for Actions per visit?

Check out the dashboard screenshot with annotations and (for the same period of time) the second screenshot with the correct values as shown in Visitors>Overview.

This problem occurs for any period of time.

Do the reports in “Actions” of list of Page URLs and Pages Titles look OK ?

Yep.

Couold you please send me access to your piwik + login+pwd + bug description by PM please?

I’ve just sent you a PM.

For the public record, I noticed that the problem does not occur in newly created user accounts!
