Client ip is not visible in the logs except for /oauth/token api log

I have enabled Trust Token Endpoint IP Header for my application and I am passing auth0-forwarded-for header in the following APIs,

POST /dbconnections/signup
POST /oauth/token with grant type password
POST /oauth/token with grant type refresh_token

But in the Auth0 logs I can see the client IP only for the api /oauth/token with grant type password. Other two API logs just have only the field IP and client_ip is missing. How can I see the client_ip for the signup and refresh_token apis ? Also, Is Rate limiting for APIs works based on client_ip ?
