Looking at those graphs it looks like the aircraft didn't pick up the glide at the FAF, and the crew had to disconnect and chase it down by hand (no a/t). The high ROD close in is the clue.
Possibly the workload with the config changes may then have lead to not increasing the thrust from idle when needed, especially if an inexperienced pilot is on the controls, who does not interpret the increased back load on the yoke as a speed loss. The rate of speed loss with the flaps at a landing setting and the thrust at idle is of course quite high.
