Problem replace "empty lists"

I followed the solution that was posted time ago (showed on the first picture). When I do the same process, the results are given in different list, not are replaced in just one list.
Why does this happen?

Hi @paula.segura.h

your ootb List.ReplaceItemAtIndex is not the same one as in the first screenshot. That one is a custom node from the clockwork package i believe. The dfference is that the custom one allows to replace items at multiple indexes in one list whereas the ootb one replaces one item per list only.

Thank you @Mostafa_El_Ayoubi

I downloaded the package and now is all ok!
