Witcher 3 Reshade settings not available

I am an absolute newbie when it comes to both Reshade and code but I have been getting error code x3004: undeclared identifier 'BUFFER_SCREEN_SIZE' and error code x3004: undeclared identifier 'BUFFER_PIXEL_SIZE' and error code x3004: undeclared identifier 'BUFFER_ASPECT_RATIO' in the Witcher 3 . All these are blocking most reshade settings. Can anyone help?
