Numbers on bar index on visualizer doesn't increase after n number of copies using si(mindex)

Im using si(mindex) on bar index to test the visualizer. the number on editor is increasing but the number on bar index field stays the same for all elements (numbers not increasing on each copy). but the si(mindex) works fine on other parameter such as position.

Other user who is using device on android 10 finds the si(mindex) working fine on bar index. im using lg g7 running android 9.

Is this device/android version related issue or am i just doing this wrong?This is the klwp file.

Make sure you are changing the max number of bars. Si(mindex) won't work if the limit is not in the proper format. BARS_##
