In the My Squad screen, if you go to your lineup on the right and scroll down to your first bench player, look at his fielding attribute in the bottom left of the screen. As you scroll down through the rest of your bench players, they all keep your first guys fielding #, but if you scroll up, it shows their actual numbers. Any time you scroll DOWN in your bench, the number won't change, but scrolling up works fine.

Not a huge deal, just kind of annoying.
