I am sorry, but, I can not reproduce your issue on my system. I believe, this is not so common to other user since I don't remember seeing similar issue reported by others before. Below is my screenshot when I use the "Access Fences instalntly with hotkeys"

BTW, can elaborate on what do you mean by "Two Desktop" mentioned on your initial post? You mean two Fences Desktop pages? or, something else?
Thank you,
