Windows 10 - Fences Keep growing vertically!

Love Fences, worked very well with Windows 7 in my current setup. However, now, the most annoying thing is happening. I use a laptop that is docked and connected to 2 external monitors (for a total of 3, if you count the laptop screen). 

While the fences I have created move appropriately upon docking and undocking and stay in the proper position, the fences themselves grow vertically beyond their bounds, leaving empty space at the bottom. 

What is causing this?  I cannot get it to stop. I can correct it by sliding them back, but eventually, they get back to this again. The Applications Fence really shows how it goes all the way past the bottom of the desktop and it is terribly difficult to grab onto to fix.
