Labeled Keywords are a very specific data construct that provide fixed lists of values. To my knowledge, they are only used on Flukebook.org for things like fluke “distinctiveness”, which uses a fixed list of scores from 1-5.
So your Labeled Keyword list should be empty, and I see your keyword list correctly populated. Labeled keywords are likely to become custom fields in our next generation UI, so I don’t recommend starting to use them currently.
