We have a project that syncs with Github. A pull request was created in Github against the default branch. That PR synced with Upsource and Upsource indicates the branch is being tracked by the review. The diffs on files in Upsource, however, is showing all sorts of changes that are not part of this PR. It is not the same diffs showing in Github and is not the diff with the default branch.
I really don't know what is going on at this point or what to do. Any advice would be appreciated.
