When they removed dml/dmr they said that they combined both dl/dr and dml/dmr. So they are right. Just divide fullbacks square in the half - and you will have dl in first half and dml in second.
Same goes to aml/amr. Divide his zone and you get aml/amr and your lst/rst.
Not sure about other positions but those two for sure changes players position/movement in the game
