did you mess with this file or something. The offsets for some data is completely wrong.
edit: it looks like the save has many corrupted portions to it.
I tried to save your party and box, but only the first 2 boxes can be saved.
(just drag the file into PKHeX. the rest of the data on this save is from one of my older saves)
test
edit 2: in case you're curious, to why the other boxes can't be salvaged
edit 3: clarification on which parts is from your save, and which parts are from mine
