Hi Bo, I'm pretty sure this is what's happening on Merion 16.
I went to that spot on 16 using the Play One Hole facility here and after 7 pitches/chips I was in the same spot of your replay:
I then tried to move the aimer as if I was adjusting for cross wind. As soon as I try to move it the aim box "snaps" to this position. From 132 to 15 yards.
I left the aim box right there and hit the shot. Here's the replay.
I got the same result as you. Way left of the green.
After that initial "snap" the aim box is no where near aimed at the pin.
That will happen on some holes because of the terrain between the ball an green. Based on this result I'm lead to believe you're aiming from the player view as I did. Try using the Zoom view to adjust your aim.
