I have implemented lookup table with names of employees…

but the problem is the names needs to be same as in lookup table

for ex: when i type in chatbot what is sohail employee id,it doesnt recognize as in lookup table it is Sohail

I have added case_sensitive=False also in my config file

attaching my config.yaml and nlu.yml

config.yml

pipeline:
# # No configuration for the NLU pipeline was provided. The following default pipeline was used to train your model.
# # If you'd like to customize it, uncomment and adjust the pipeline.
# # See https://rasa.com/docs/rasa/tuning-your-model for more information.
