rasa 3.1

rasa version==3.6.15

python version==3.8.18

in nlu.yml I wrote regex limit to [0-9]{11}, \d{10, 11} and if I write less or more this limit it still gives me the values even if limit isn’t reached in actions.py

replace line - name: RegexEntityExtractor to:

- name: RegexEntityExtractor
  case_sensitive: False
