A few comments on this thread following my experience in the new(er) version of the software (2024):
1. The file path was as attached in the screenshot below,
2. There is a '-' (negative/minus) sign in front of the coordinates in my case, I thought it was just a dash, but it actually moved the coordinates to the negative side of X and Y axis. After removing the '-' the (100,100) coordinate works quite well
3. In my case the application (AS) did not have to be restarted to see the changes. Just save the file (maybe close it too) and run "Mgt Tools" again, should display the window with updated coordinates
