Thanks so much for the fast and detailed answer!!
Yes, that is what I was asking. I see, so in essence, prodigy train arbitrarily chooses one of the annotations to go with? The link you provided seems to suggest that the span annotations would be merged instead though, and not dropped. Please let me know which one is the case and how we can control the behavior?
I believe it was a mix, as not all examples were annotated by all annotators (mostly due to time/cost limitations), but there are definitely duplicate annotations.
We did use multi-user sessions, and have not modified feed_overlap, so it looks like that lines up!
