Pull request to prod branch doesn't link all Jira items

[Lee Palisoc]

How is it possible that when I make a pull request to my production branch, the PR doesn't link all the Jira items mentioned in the commit history and the PR description?

My branching strategy is dev -> test -> production. All the Jira items I worked on were mentioned and properly linked during dev and test deployments (the Deployments tab in the Jira project also shows all of them).

But when I create a PR from test to production, only 14 items are linked, even though I have included the entire test branch's history using the {{commit_messages}} placeholder. We have 35 Jira items properly linked in my PRs for dev and test.
