Milestone Churn Graph shows negative numbers

Summary

On our project, we've encountered a churn graph that's gone into the negatives (currently at -3 open issues).

Steps to reproduce

I am not sure. We've worked on this milestone for a month now, where we've opened, closed, fixed, moved, merged several hundred issues in 8-10 different repositories. So I wouldn't know where to start.

I do know though, that this is a calculated value - as if we close an issue or create a new one, the graph moves immediately. It also changes if we change the milestone date (which we also did)

Example Project

On-premise. I can't export these projects.

What is the current bug behavior?

As of writing, our Churn graph has moved to -3 open issues, while we still have 34 open issues.

What is the expected correct behavior?

The churn graph should stay at 34 open issues, as that's what we have right now.

Relevant logs and/or screenshots

Numbers. Our milestone currently has:

  • 198 issues
    • 34 open
    • 164 closed
  • 112 merge requests
    • 12 closed
    • 88 merged
    • 12 open
