How to know which ticket is preventing me from deleting a completed sprint

Question

For some completed sprints, I have this error message when trying to delete the sprint. The message says «this ticket cannot be modified because of its workflow status», but it doesn't specify which ticket...

How can I know which ticket is preventing the deletion ?!?

I want to delete a completed sprint, not closing a sprint...
The sprint I'm trying to delete is already empty.

I have some basic questions about your use case.

* Why are you trying to Delete a sprint?
* Are you actually trying to Close the Sprint and Open the next one?

* If you want to Delete the Sprint, actually delete it, then you should be moving all the tickets out of the Sprint before you delete it. If you want to Delete the sprint and all the tickets in the sprint, then you should delete all the Tickets first before trying to delete the sprint. 
* Short answer, the sprint should be empty before you try to delete it.
