The test simply moves a piece down to the bottom, steps, and repeats everything.
In your case, it seems like three pieces landed.
Intuitively, this seems like you either trigger the events multiple times at once or trigger them in the beginning when there is no piece there yet.

yeah , I fixed it thank you very much
