That does look suspicious. How many did you accept?
What would probably be most helpful for you is a recipe where you can use the patterns file and then use the ner_manual interface. This is a small gap in the recipe suite at the moment, but it can be easily assembled with the current pieces. Ines gives a code example here: How to use a spaCy pattern in Prodigy
I do wonder why ner.teach didn’t seem to work here though, as what you did seems okay to me. My first thought is maybe there aren’t enough accepts, but if there are plenty of accept cases, I’d like to make sure there isn’t wrong with the recipe.
