Config variable for packaged game


Just curious how config works for packaged game, I use config variable

In Saved folder I have Engein.ini file, when I changing parameters there, it changes for stand along game running from editor. Then I packed game without use pak file - for test purposes, I run game and see variables with no default values but like they been read from config. In time there is no configs with this values, I changed it in User local folders. Can anyone could explain me how it works for packaged game, can I edit this variables?

I used C++ Gconfig instead to read value.
