filename incorrect when creating new comment

Hello - 
Am trying to create comments on a file but apparently when it saves to the csv it is not correctly writing the location file.

Saved filename : 
c:Users\**USER**\...Modeling.py

Actual filename : 
c:\Users\**USER**\...Modeling.py

I can fix it after the fact in the CSV however it does not allow me to view the comments, or edit them until I change the filename in the CSV.
