Taskbar in Windows 2012 RDP not showing on multiple servers

I have the following environment.

I have multiple Windows 2012 Server R2 running Terminal Services
Servers all have identical apps installed
I have GPO for file redirection for AppData to a shared network drive
Which ever server a user logs into they are using the same shared appdata location

My problem is that when a user logs into one server and adds icons to their Taskbar and then they log into another server the taskbar does not have those icons.

I understand based on my previous post

https://www.experts-exchange.com/questions/28582928/Items-on-Start-Menu-Windows-2012-and-Windows-8-AD-environment.html

that the start menu and taskbar are not redirected and therefore not saved. However, regarding the Tasbar icons, I actually see them in the directory \AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar which is in the shared location.

What's even more is that if the user creates the icon from the second server that icon now appears once on the taskbar but a second time in the folder location with a (2)

Any idea why this is and if there is a way to share the taskbar.

Thanks,
