This is a problem I should look into. (There must be a bug in the save transfer)
The closest we can do is try to look for a "NudeByte.sav" file in the old version's folder. If there's one, do this:
-Make a backup of your current save data first (even if the dolls are lvl 0) using the Save Transfer. (While Save Transfer is running, choose Export. Rename the generated file to however you like and set it aside. It's a just-in-case)
-Copy the "NudeByte.sav" file from the old version's folder to the Save Transfer folder.
-Import it using the Save Transfer.
Run the game and see if this works. However, this will also mean it's an older version of your save data. (Progress will be lost)
