How do I re-enable merged MRs to close issues automatically?
Version: GitLab Enterprise Edition 13.1.4-ee
Our MRs used to close the issues that were in the MR description as Closes #12345 for example.
For some reason, now the MRs are merged and the issue is still left open and I need to manually close.
Troubleshooting attempts
I am at a Maintainer level.
I looked at this doc: https://docs.gitlab.com/ee/user/project/issues/managing_issues.html#disabling-automatic-issue-closing
But under Settings -> Repository, I already see the box checked for “Auto-close referenced issues on default branch”
What other settings should I check or what else should I look at?
Thank you!
