Sprint issues all to backlog after upgrade Jira, but issues still in a Sprint

Jasper

Hi,

After upgrading to version 7.10 I found out that all my Sprints are 'cleared', at least.. there aren't issues visible in them anymore:

But there were issues in them before the upgrade and you can still see that when you search for a specific issue. The Sprint is visible in there:

The same when editing the issues:

This is happening to all my projects.. how to fix this? Because they are saved somewhere in the correct Sprint, but not visible or something like it..

Did you try (full) reindexing?

If it did not help, have a look at here.
