RFI/Button Call vs 3bet is different from "vs 3bet call range IP"

[tese]

Hi, only filter are:
"Number of players: From 3 to 10"
"Hero's position: BTN"

Why the result of (RFI*Button Call vs 3bet)/100 is different from "vs 3bet call range IP" stat ?

The 2nd includes hands where players limped 1st. RFI is only when it open folds to you.
