I've had the same issue a number of times and it's getting really tiring. I think it happens when the game deems the freekick to be from a shooting positon even though the positon is a long long way from goal so 4 players line up in the wall and leave 3+ players unmarked for a nice chipped ball into the box. There needs to be a differnece between a free kick from genuine shooing range where you would like to have 4/5 players in the wall and one from much further out where 1/2 players would be sufficient.
