Ok, what I have found, if Cloud save is Enabled then in My Documents saved profile will not appear.
Because steam cloud is enabled, then it creates your profile in
\Steam\userdata\********\227300\remote\profiles\*******\save\
227300 is ETS
\save\ it depends on how much saves you have, there will be several folder, but biggest number will be last save, lets say i just created 4th save,
Open folder 4, and there you have game.sii file, decrypt, and edit in Notepad++
