JKSV Restore Help

[ikrtheblogger]

So I have a hacked Switch that is running Atmosphere on an EmuMMC. I used JKSV to get a copy of my save file for Pokemon Violet, and I was able to edit it using PKHex and save it. However whenever I use JKSV to restore the newly edited save file, it says it restores it and makes a backup but when I load the game it has none of the changes. I’m using a cartridge version of Pokemon Violet and only ever boot into the emuMMC.

I am having the same issue, I've tried to restore it on both sysNAND and emuNAND and neither is showing my backup up. But if I open it on pokehexk I can see every data correctly. 
Do you have to reach a certain point t in the game history to be able to restore the save file?
