Analytics vs Api Followers/List results

Hi good day, I’m having trouble on the analytics total followers count in https://analytics.twitter.com/user/LobsterNYC/home vs the rest api total results of follower in https://dev.twitter.com/rest/reference/get/followers/list

cause like we have 18 followers in April 2017 as shown in analytics but when pulled on api it only give us 3 followers for the month of April 2017.

I am not sure what I am missing on the api doc. Any help would be much appreciated.

Thanks
