I know, I've run into the same thing. Someone came up with the solution I suggested. I don't know why it works, it doesn't seem like those two things should have anything to do with each other. All I know is that it worked when I tried it. When you're playing a game and the swing info box doesn't appear, pause, go to gameplay options, and turn on "Pitch Select Display". Then go back to the game, and the swing info should start showing up again. Once you do this once in a game, you can turn the "Pitch Select Display" off again. Hopefully this will be patched.
