Are you on Android? On Mac and PC you keep every file, on Android the download replaces the prior download and that's normal. Inside the download all the files get compiled together into the most recent build. So even if the other versions are gone, all the data is in the one file you do have left.
It is Android. And I got it figured out. I made a save on the memories page using the one that worked. Then downloaded the other and now both are on there. Thank you. This game is everything I was hoping and more.
