ContextCapture: 'Connot Find Retouch File'

Hi, I am having some difficulty, one of my scope of the project is to using CloudCompare Open Source Software for Editing. I already follow the tutorial for retouching as I want to edit the mesh in 3rd Party software. The file is in OBJ format. After some editing in CloudCompare and the file is save as OBJ, I'm trying to import the Retouch file back in ContextCapture but a notification 'cannot find retouch file' pop up (as shown in the figure below). Can someone explain why this happen? or there are some issues with the data format. 

Thank You.
