It could be for a couple of reasons
1. Check if the number of distinct values in this column exceeds the current limit of 1,024 distinct values. Reference: https://docs.databricks.com/aws/en/genie/knowledge-store#-prompt-matching-components
2. Check if there are duplicate entries in the column, where both GATE_OUT & GATE-OUT exist in th column.
3. More importantly, it could be that the entity matching state is stale. The state is created when the Genie space is created. However, if the data is refreshed, you will need to manually refresh the state.
- In UI, toggling entity matching on and off will refresh the state that is used for matching values. You will see a spinning wheel in the UI, for example, see below
- If you want to update the Genie space, you can also do it programmatically: https://docs.databricks.com/api/azure/workspace/genie/updatespace
I hope this helps!
