Choooiii​  These are all backups of the save with the same number, which is why the game isn't reading them.  You can delete the .verx extention to make each one a usable save, but you'll need to renumber two of them—change the 3 to a 4/5/etc.—so they don't all have the same name.

For reference, the game will only read saves in the format Slot_xxxxxxxx.save , where the Xs stand in for hexidecimal (0 to 9, a to f) digits.  For example, these are all viable save names:

Slot_00000003.save
Slot_0000000a.save
Slot_00000012.save
