Ranking shown incorrectly


Greetings, i managed to grab another WW rank1 the other day on Kin’Garoth heroic.
It shows 100% rank, meanwhile its only rank 2 FeelsBadMan but whatever - it was shown as 100% on my statistics https://www.warcraftlogs.com/character/eu/blackhand/wajoba aswell but is now shown as 99% and that feels kinda sad since all the others stayed even tho somebody managed to get a higher number.
As a comparison - uluu’s logs are the same but his best historical is still shown https://www.warcraftlogs.com/character/eu/blackmoore/uluulu . We both got Coven #1 at some point but we both don’t have it anymore and it sill gets shown. Somebody got a reason why this could be?

Current kingaroth ranking list, showing me as #2 which is correct, but historical should be #1 since my rank is from Jan 2nd and #1 is from Jan 3rd.

Coven heroic, historical rank 1 on Dec 13th nearly a month ago probably around rank 100 now but still showing on character statistics due to being historically rank 1
