Microsoft Offine Picture Manager question

I just loaded a bunch of pictures into Microsoft office Picture manager and I am unable to reposition any of them to different locations within a folder or group them by subject matter, etc. I’m not talking about sort by or group by under “View” I’m talking about moving a picture up three rows or flip floping it with the picture next to it.

Also, the same thing happens if I pull any of the pics into a folder on the desktop. I used to be able to reposition prints within Picture Manager and on the desktop but can’t do it now. What gives?
