Opening a CC .fla in CS6 replaces symbols and duplicates layers, frame labels and code on compile.

So when I compile an fla in CS6 that I built in CC, It replaces all my symbols and puts "m&#058" in front of all the names.

Not only that, but on compile, it duplicates layers and frame labels within selected movieclips and then spits errors out calling duplicate functions and frame labels as the issue. Has anyone ever run into this?
