Inaccurate number of followers

The problem occurs when I am requesting the followers of the streamer deraphin. No other user is affected (afaik).
I am continuously getting two followers less than the total number: 2,682 instead of 2,684
This happens all the time by every request. I have tested this today and four days ago.
So this is not a problem of changing followers while requesting.
Additionally, I am not using the offset at all. I am using only the cursor.

Thanks for your help!
