I have a problem with JIRA Agile showing incorrect information in the sprint report and (because of that?) in the velocity chart. We started a sprint of 23 SP's, but after ending the sprint (with all stories resolved) the sprint report shows 3 issues that where not completed (but were not included in the sprint when/after starting the sprint.
Does anyone know what might cause this behaviour? Or how to fix this (even at the DB level if necessary)?
I hate my reports to be incorrect :-) so any help would be appriciated!
