Hi @PaulK
It looks like this particular photograph was manually uploaded to ACW 3 different times. The long list of IA tasks on the obrowse page corresponds with each annotation/ID job for every time it was uploaded (7 annotations for this photo times 7 ID jobs multiplied by 3 for each time it was uploaded, etc.)
Additionally, it looks like this is the same photo from this Community post: No matchable detection on a correct annotation
Yes, feel free to delete the obvious duplicates.
