WIP Merge Request was Merged?

We have has a WIP merge request merged and we are unsure as to how this could happen.

Steps: (no command line was used)

  1. Had a merge request for branch2 open
  2. We branched from develop (created test-branch)
  3. Merged branch2 into test-branch
  4. Changed things in test-branch
  5. Made merge request for test-branch into develop
  6. Merged test-branch into develop
  7. Checked merged and branch2 and test-branch had both been merged into develop in that order.

Screenshot was taken from our merged tab in the merge request window for the application. wip-merge-request
