Powerplay faceoff line change doesn't work

While editing the powerplay lines in the franchise mode, I noticed that the center of the line is set as the player in front of the net. Because I wanted a player X to play in front of the net, I put him as the center. At the same time, I wanted another player to take the faceoffs, so I used the edit faceoff line under team strategy settings, and put player Y, which plays the right wing on the PP unit, to take the faceoffs. Unfortunately, this change wasn't saved and after looking at the line again, the player X was once again listed as the one who takes the facoffs (despite me changing it). Changing it during the game in the pause menu does work, but only for that game.
