The latest version of Start 10 and Fences are installed on my Win 10 desktop. All appear to work properly except the icons listed in the Start 10 Fences folders are not complete. Only about half the icons in a particular Fence show up under the associate Start 10 Fences folder. I can find no pattern to which icons are left out and multiple settings in both Fences and Start 10 result in the same problem.
A screen shot of an example with the Graphics Fence is shown below. Note there are actually 14 icons in the Graphics fence (on the left) but there are only 7 icons shown under the Graphics Fence folder in Start 10 (on the right).
