Authorship for Bitbucket issues, PRs etc
GitLab is supposed to leverage Bitbucket identity bindings of its users to automatically make them the authors of various importable elements, such as issues, Pull Requests, various comments.
In practice it's never worked for Heptapod, even if running with an administrator account. Last time I looked, I got the impression that the author was being referenced differently in the import data, compared to the identity bindings, at least for some Bitbucket accounts. This may be due to a stronger privacy policy on the Bitbucket side.
At this point there's no certainty. The chances that the Heptapod changes compared to upstream GitLab could be the cause of it are low, but this needs to be retested on Heptapod 0.12.
