Closing the Sprint will move the outstanding issues to the Sprint.

[SH]

Closing the Sprint will move the outstanding issues to the Sprint.(Sprint created but not started)
But it is different from one issue to the next.
Some of the issues are back into him.
Other issues will enter the pre-generated Sprint.
Sometimes closing Sprint 1 will expect to enter Sprint 2 but they will enter Sprint 3.
Sprint has set a year in motion,
Odd numbers enter odd numbers.
Even goes into even numbers.
1>3>5
2 > 4 > 6
Issues not complete as shown above are introduced.
I don't know the cause.
Please check.

(jira 6.4.11)

[Troy Spetz]

We use JIRA 7.9 server version.

We have never experienced this problem.

On closing the current sprint, we get to choose which future sprint will *all* incomplete issues (from the current sprint) be assigned. They have never been randomly distributed across multiple, future sprints.

Your JIRA version is quite out-of-date. It may help if you upgrade to the latest JIRA release (according to your license agreement).
