Hi @jwaite, welcome!
The same issue was reported last week for belugas: Automated Annotation off
This is a result of training on “clean” data where pictures used are of ideal conditions and then presenting the model with more “messy” real-world images where conditions are less uniform. I recommend deleting the incorrect annotations and then manually adding new ones in the correct place.
Once you’re satisfied with the new annotation placement, you can choose “start a new match” from the image menu to re-run identification.
