remote debugging doesnt view source in library files, asks to edit path mapping settings

I re-installed windows and Now I can't get my python remote debugging working again.  The debugging works well enough, but when I jump into a function that relies on a python library then I get an error messages i've seen before complaining that it can't find the source file.  In my particular case I'm using the pandas library and I get the error message in the attached image.

As I understand it, pycharm builds local skeletons of remote library files.  And indeed if I view my  'External Libraries' -> 'Remote Libraries' folder, I see that indeed the pandas library is there.  

I've attached my debug settings.  

Any suggestions would be helpful.  Thank you.
