It is not a bug riot discussed before I believe. The whole system works differently for each player and gives an ever-changing scale that you may need to reach while taking into account your behavior, other people's behavior in general, and reports stuff like that you. Like I have a friend who got honor 5 within a month of the new season even though he averages about 1 to 2 honors at most a game if that. Like I was stuck at honor level 3 for months then once I hit 4 I quickly started going up the ranks which were only about 2 to 3 weeks per checkpoint for the first two average about 5 games a day at most with only 1 to 2 honors a game. Then checkpoint 3 took me longer since I haven't played much.
