Diablo 2 Single Player Characters missing

When I load Diablo 2 and select single player it takes me directly to the screen to select a new character to create even though I have characters in the save folder within the Diablo 2 directory. How do I get the old characters to appear

The Characters were created on a Windows 8 Computer and I moved the via a flash drive to a Windows 10 computer I do not know if this matters

Put them in /users/games/Diablo II, or something like that.
