Arranger: Count down number of REPS not appearing correctly

From the manual: “The number displayed to the right of the currently played pattern is a count down of how many repetitions is left to play of the arrangement row.”

I do have the correct number of total reps listed to the right of this number but it doesn’t count down like the manual says it should which makes it difficult for me to tell where I am in the song.

Do I need to adjust a setting or something?
