I exported my template settings from 2.5 as a .json file (named techsolv.json) as part of an iterative upgrade process I was doing. After upgrading again, I moved the json file back into the config directory. I then imported the new json file.
But the default settings did not change! The did not change until I moved the default_config.json out of the config directory. THEN it worked. Why is that?
It appears that the alphabetically first file is imported regardless of what is selected, perhaps?
