live.step problem

Hello,
I'm trying to make a click metronome for a couple of scores. I used the live.step object to control the upbeat an downbeat of each bar. Unfortunately it doesn't work correctly: after the first pattern it doesn't start at the beginning of the bar but at the last step of the the previous pattern. I'll attach the patch just to have a look and hoping someone will help me to find out the problem.

Thanks in advance.
