Valorant account has incorrect top rank

Site here shows Peak Rating Platinum 3 EPISODE 1: ACT 2 however during the same act I got diamond 1 and also won a match in diamond. Game client also reflects this.

Per the info “If you’re new to the site we may have missed old matches.” however the API is still able to see my plat 3 from episode 1 act 2? In the same episode/act I got diamond? Not sure how that is possible.

the last recorded match from E1A2 was in P3.
we did not record peak rating in the first episode on a per-match basis, so in this case it’s going off of the final recorded season rank (“end rank”)
