Below are the details of pipeline and config used
Pipeline ( I do not want to use DIETClassifier)
# Configuration for Rasa NLU.

case_sensitive: false

Config
version: "2.0"
nlu:
- regex: account_number
examples: |
- \d{10,12}
- intent: inform
examples: |
- my account number is [1234567891](account_number)
- This is my account number [1234567891](account_number)
- intent: greet
examples: |
- Hey
- Hi
- hey there [Sara](name)
- Hi [Sara](name)
It works fine when I replace small(en_core_web_sm) with medium(en_core_web_md). Any pointers on what is causing the issue.
