Missing my Rank on leaderboards

Is something going on with Rankings. I just did a 100 and noticed it was in 3 minutes and didnt get notified I made the leaderboard. Curious I looked it up and it was best score for HC Seasonal Barb for that rank but I wasnt there. Its possible im on the leaderboard already so I dont know if you are only allowed one entry?
Not a big deal as I wont hit 120 anyways.

Sometimes it took a while for leaderboard to refresh.

If you were on the leaderboard already with a higher clear, it will not register the lower clear. It only alllows one entry per account.

Are you referring to the web page leaderboard
or the in game Leaderboard?

The web site is not refreshed frequently at all.
