Custom Resolution Utility (CRU)

[Kanisteri]

I was trying to use CRU to remove the 1080p 59hz option but instead, it wont remove it and it also adds a 50hz option in the Windows Refresh rate settings. Nvidia Control Panel was only showing the 60hz option but games were defaulting to 50hz. Actually, modifying anything with the CRU is adding the 50hz to 1080p and I cant get rid of the 59hz. Deleting the active profile gets rid of the 50hz. I tried using it with and without any extension block and with and without GeForce Experience.

Screen is a LG W2453, a 60hz 1920x1080 display with a DVI.
Video card is NVidia GTX 560.
OS is Windows 8.
