Project default reviewers not populating in pull requests

Jira and Bitbucket (Atlassian Labs) v2.10.12

When we have default reviewers setup in a repository, pull request creation with this extension works perfectly, but if we setup default reviewers at the project level, those reviewers do not get picked up when creating PRs with this extension. (Those reviewers DO get added when creating PRs from Bitbucket’s Web UI.)
