How to clean up a Project Velocity Report that is referencing sprint from another Project

[Scott Buratt]

When running a velocity report, I am seeing sprints included from a different Jira Project, which effects the report value.

I see the following

---

Go to board

Sprint s23.10.I1.S3 appears on the following boards:

Clients - Scrum (these sprints look like "cxx.xx.xx.xx")
Server - Scrum  (these sprints look like "sxx.xx.xx.xx")

---

When looking at the velocity chart for the "clients" sprint, I see sprints from the "server" sprint (where the server sprints have invalid values)

Not sure how to clean this up but it's making the "client" Velocity report unusable.

(note that this is a recent phenomena)
