1. This exactly the case, it was putting all new icons under my Gaming fence, but I never set fences to do this, it just made the change on its own.
2. I have one other non-related issue, and I'm not sure if there is a fix or setting for this, I have (4) fences, one of them organizes alphabetically, the other (3) are set to nothing, I like arranging them in my own order. The problem comes whenever explorer crashes, they get scramble, or sometimes when I restart or shutdown my PC, on desktop load they are scrambled. I either need a way to lock them or save a backup of the file that stores the layout.
