fc 25 commentary not changing ( possible bug)

i have put them on random, and it always put itself back to ( Derek Rae and Stewart Robson) every time,  i have 64h of playtime in the game now and i realized that i never heard not once Guy Mowbray and Sue Smith. i checked the option and here it was on Derek Rae and Stewart Robson only. Could be a bug in the game.
