Hey @pmbaumgartner,

You shouldn't need to re-annotate the same first example. I think this might be related to [another thread](https://support.prodi.gy/t/prodigy-shows-examples-already-in-db-when-feed-overlap-true-and-using-a-named-session/3121/3). If you're willing to try out a beta version of a fix to see if it covers your use-case, send me an email at justin@explosion.ai. Thanks!
