.x file reports bone count as doubled

Using kwAnimation: I'm loading in .x files with 42 bones (using the Panda exporter), yet on compile the error states there are 84 bones. I'm stuck on trying to "fix" this issue. Any idea what to do here?

However, If I use the kw exporter, then the compile error is "there is already a key set" or something like that. I matched my model export exactly as shown in the png files in the readme.html for kw Animation. Any ideas on how to troubleshoot these issues?
