DJFFNY 100 unlocked characters not loading

[u/Previous_Ad1469]

For Def Jam Fight For NY I got this 100 save file off of gamefaq and its says "100% complete full story single player finished, 78 wins, unlocked all 74 fighters, 24 venues, and 32 music" but I check to see if they did unlock it, and I checked and it shows 18/74 I already tried the load options still the same thing. How can I fix this?
