Can't do full edit of players or manager

If I'm wanting to edit a player and make them have long socks, for example, I can't get to the bit that lets me highlight the one I want. I use the left and right cross buttons, but all that does is take me to the next page. Can't go down. Same with certain areas of clothes for managers, I can select a few things but most tabs wont let me go on and highlight and click the one I want
