Problem after saving cloned editor

When i need to work on different functions in the same file, or in any case i have to work on different sections of the same file, i use clone function (see image below on attachments files section).
The problem is that when i save the file, after the 3a/4th time i save, all the cloned editor line up on the same line of code, they move by themselves! Therefore every cloned edtior is automatically placed in the same function, but in doing so i lose all utility of using a cloned editor.

This make me lose a lot of time! ;/
