So from what I've gathered from the research of how four kids does it they try and remove certain phrases and alter names for the following reasons.
References to satanic or demonic (in their opinion) references or names which is why the word devil fruit was turned to Cursed fruit.
References to alcohol, the reason why everyone in the four kids specifically said what they were drinking was juice of some kind.
References to smoking, hence why smoker was named chaser
References to gambling, this is my suspection that they changed Ace to trace since Ace is the name of a playing card and playing cards that are used for gambling, weak reason but four kids one piece had a lot of those.
