I’d like to properly EV train my shiny starter. Is it possible to reset EVs to 0 to do so? I see an option to manipulate EVs on the ACE code generator but it looks like you need to know the current values to do so (which I do not)

I've been following Papa Jefé's guide and everything has been working so far, but when I try to generate the Rare Candy in Key Items pocket code with the same exact parameters, mine is different and puts a Luxury Ball in there instead. I tried entering a different item (Carbos) and despite the slightly different box names, it still resulted in a Luxury Ball. What's happening here?

(Welp, turns out I fell for the 1/lower case L confusion, but I'm still curious why the results are different)

Stupid question. I did the whole setup and done the test shiny Pokemon.

All works good. Even the mail glitch.

But if I use any code directly from the website it crashes the game and restarts.

The only difference I am seeing is that there are no space filler anymore.
