Valkyria Chronicles 3: Unrecorded Chronicles

[Andysun]

I'm currently having issues trying to use post-game (after having completed the campaign once) saves from my PS Vita.
All other saves prior to finishing the game work but when attempting to load the post-game save it simply starts a new campaign with all stats wiped (no currency, exp, only first mission available to play). Anyone else having this issue or know of a solution?
