Debugger Path Mapping File separator Error

Hi 
I am trying to setup a debugger with maya. 
I have setup using this guide. 
https://matiascodesal.com/posts/how-to-use-pycharms-remote-debugging-with-maya/
I do have to use path mapping due to a remote deployment of a package . 
here is my pathing 
C:/dev/pib-maya/src/python/bptmaya=B:/pibrez/dev/aaucoin/pib_maya/6.12.12.dev1/d7bd1f4a812a21971b1e2a02ba5649ea4cba3a38/python/bptmaya

this works and I am able to stop at break points  but I am not able to see the file I am stopped in the mapping is converted or something.  it looks like it converts the file separator
C%3A%5Cdev%5Cpib-maya%5Csrc%5Cpython%5Cxxx_aaucoin_dev.py 
 

Is there anyway to fix this?
