"So the problem here is that we don't show RANKED TEAM Elos ANYWHERE in the summoner profile right now.
What you do see on the summoner profile is the ARRANGED TEAM Elos. That is to say, the Elo that people got during pre-season playing arranged teams 3, before ranked teams were introduced.
We're aware that this isn't exactly the most useful information to represent here (since you can't play arranged 3s or 5s anymore), so hopefully we'll have something more meaningful there in the future." - Riot Taco Storm
