PT4 is a bit confused. at FR tables it writes UTG+2 instead of MP.

SB posts SB 0.5 BB, BB posts BB 1 BB
Pre Flop: (pot: 1.5 BB) Hero has 4 5
UTG raises to 3 BB, fold, fold, fold, fold, fold, BTN calls 3 BB, fold, fold
Flop: (7.5 BB, 2 players) 5 4 Q
UTG bets 4 BB, BTN calls 4 BB
Turn: (15.5 BB, 2 players) 9
UTG bets 8 BB, fold
Spoiler: show
So it removes MP3 instead of UTG.
Thanks!
