In Agile Central (Rally) I'm seeing my release or iteration listed twice.

This issue can also cause a filter for query on a release or iteration to Not show all work items associated to that release or iteration.
They keys that make a release or iteration unique are the same name and start & end dates.  If these are all the same, they show as one listing.  Conversely, if anything is different, you may see duplicates listed. 

Here's an example of a release but the same holds true for an iteration. 

This screenshot shows a duplicate listing of release "2017 Q2".

Duplicate Releases

Reviewing this release under Timeboxes, we see that the Release Date for one of the projects is out of sync with the others.

Navigate to the top level project with project scoping to include child projects and make sure that all Start Dates and Release Dates are identical for each project listed with this release.

Bad Release Dates
Correcting the date, they are now all in sync.

Good Release Dates

Now when we review the listing, there is only one entry for 2017 Q2.

No Duplicate Releases
