[Qt Creator] default build directory changing

linux
#1

as you can see below the screenshot (after build), when I compile/build my app, Qt Creator generate the build directory level as same as ../%project_directory/ level. it looks dirty for me. so I tried to change this with OPTIONS > build&run > General Tab > ‘Default build directory’(setting in option, screenshot below) but it’s not working.

the general setting in options > build & run should work, i have it set to obj and my object files end up in an obj folder inside the project
