Problem replacing element in firebase

[AcrobatEpee]

Hey ! So I have this path on my Firebase :

And I want that when the user deletes B, C takes his place.

I made this :

This is the final block

This is the blocks where I save my values when the user picks from the list

And finally here is the blocks launching the final procedure

The value picked gets deleted correctly, but the value after her doesn’t take its place. Thanks for your help !

Should it be like that?
