Save function has a serious problem! – Buffer Editor - Code Editor Review

I have worked through both SSH and Dropbox. Whenever I save some editing, it seems to store and reflect at a glance. But, after a few minute, it get back to the original file. I keep editing several time and am now exhaustive. I found other users who suffer from the same phenomenon in reviews. This is a critical problem, and it prevents from using this editor despite its awesome functionality!!
