How to edit characters' shield?

[Ander]

Hello.
I have a problem with PSAMod (I use it because I'd like to edit Dedede and the Pokémon). I tried to increase D3's shield, but after saving, if I open the file again the shield size has not changed, it is set to the previous value. This happens with every character, but I really want to edit only D3's shield... Since it is TOO small, and I can't change it right now. How can I fix this problem? Normal PSA doesn't open Dedede's pac...

Thanks!
