Hello,
Sorry to hear you are having issues.
If I add an icon to the middle of my desktop, let it fucking lay there, stop removing basic windows functions.
Have you try to disable "auto-arrange icons" function? And if need more control disable "Align icons to grid" too. But be remind that this only apply for icon on desktop. Not for icons in the fence. In the fence Icon will always be arrange starting on the top left.
