Random public annotations & page notes appear after sync

[lanluo9]

Thanks for creating this plugin! It synced my hypothesis highlights correctly. (Edit: I found out later that it's not syncing all my page highlights: some but not all highlights belonging to a self-owned private group got lost. This got solved by #58 (comment) )

However, it also for some reason synced 1 public annotations and 1 page notes from other users:

Could this phenomenon be avoided if I save my hypothesis highlights in a group other than the Public group?
