Why does my Epic Burndown report show a sprint from a different project?

[Deleted user]

I'm looking at my Epic Burndown report, and for some strange reason, I'm seeing a sprint from a different project show up in the report.  The unwanted sprint is called "2017.05.23 INFRA".  It is throwing off my velocity and other aspects of reporting.  Anybody have a clue as to how this occurred, and how this can be fixed?  I've been having difficult finding a way to disassociate this sprint from a different project...

I have the same problem. In my case, my Epic Burndown report shows bars representing sprints from 3 other projects plus my project. I'm using Jira cloud, classic project.

I do not have the answer but am also on the same problem looking for some resolution.

Had raised my same issue under - https://community.atlassian.com/t5/JIRA-discussions/Create-Sprint-from-backlog-gives-default-name-which-further/m-p/602009#M439

Do you have it rectified yet, or still living the same issue?
