Spawn Items when another item is dropped in bubble column or water doesn't work.

Hi here ! I'm creating a mod in which you need to clean an ore to receive it's purified form but in game the item doesn't transform itself when it's in water. 

I've seen other post which talked about that but they were too old and my procedure still doesn't work.

 Here are the pictures of my procedure and tags and triggers settings : https://imgur.com/a/WAoaHEu

Thanks in advance !
