Bad PID - you have IVs 28/25/7/17/2/22 while PID is for 17/2/22/27/19/29 IVs AND it's Ultra-Rare GBA PID, not NDS one.
For your IVs (28/25/7/17/2/22), type 2179938429 PID (Naughty nature, if you want it different play on your own )
Now my problem, any idea why legit (obtained from Wonder Card) WCS shiny Eevee is marked as Hacked/Unknown? I've made few other event Pokemons that way and never had the problem.
