I'm not familiar with Adobe software tools. I use only FFDec which is low level SWF file decompiler/editor.
ClipDepth is an object's property defined at the point where the object is placed in the frame. Those properties are for example object's name, depth (layer), Color Transformation (including translucency level), action scripts, and also ClipDepth. So it would be somewhere there and it would be named either ClipDepth, Mask or something similar.
Of course I can fix the file for you, but I guess you want to learn to do this yourself as it likely will be useful next time.
