Duplicate button = copy not working

Mauro Trotta's icon

I made a live.text button and insert on it a svg picture, and it works well, so I decided to copy-paste this button to trigger other objects, but it stop working. It have a lighter color than the original one, but every aspect in the inspector seems to be the same as the original. What am I missing?
