Hi Community
I have an issue, which I cannot find a solution to anywhere.
Previous sprints end up showing none or very few tasks, even though i know they had way more tasks included. Example below is from our sprint 19, which i know for a fact had more than 10 tasks in the sprint, yet now on the sprint report, it is empty.

Whats almost more strange to me, is that tasks disappear over time from the sprint report, because the latest, shows most tasks.
Here is an example from previous sprint, where it shows 8 tasks, however there were more than 15 tasks in the sprint

In this example, it shows only Issues not completed, but sometimes it is a selection of both completed and not completed tasks showing, but still not all.
Is there any known issue or known way of working, which will prevent this from happening?
Kind Regards
