There are two save locations if you're using Windows, Linux or Mac. The second is supposed to be a backup system, but sometimes the game uses it as a primary location for some reason.
Since you said "PC" I'm going to assume you're on Windows, in which case the backup saves location is located at:
PC > Local Disk (usually C:) > Users > USERNAME > AppData > Roaming > RenPy > CorruptedKingdoms-1547378918
If you put your saves (plus "persistent" file!) in there, as well as in your game/save folder it should read your saves properly :)
