I got that problem until I went into Spriter and gave a name for each object in the Persistent Objects panel. Double-click on the object, a little box appears, add a name. Rinse repeat until they all have names, then delete everything from your C2 file (the family, the .scml, the images, the files) and re-import it. If they show up in the editor, you have them named. Otherwise, you missed something. I hope that works!
