One more possible BUg with Kodular Firebase

I ask you to put this topic together with the possible flaws of this new update.
I am using the blocks below, and when executed, the Override block is adding a new product. So I disabled the replace blocks and store values, so there was nothing. When enabling again, the error happens and instead of replacing the item, one more product is added equal, and thus getting two products repeated in the List.

Please post blocks in English Language

Não entendi muito bem


I don’t understand

I managed to solve it was my fault, sorry
me.
