User already followed glitch

This is my code:

-------------------------------------------------------------------------------------------------------

from instapy import InstaPy
from instapy import smart_run

my_username = 'balkanski.komentari'
my_password = 'censored'

session = InstaPy(username= my_username, password = my_password, headless_browser = False)

with smart_run(session):
session.set_relationship_bounds(enabled = True)

session.set_skip_users(skip_private=False)

session.follow_user_followers(['komenthub'], amount = 10, randomize = True)

session.end()

-------------------------------------------------------------------------------------------------------
THIS IS RESULT
