Fitter ignoring PLL compensation assignment as invalid

Hi all, Fitter ignoring PLL compensation (source synchronous mode) assignment as invalid. Any ideas as to why this may be happening? I am using Quartus v 10.1

I have a LVDS receiver in my design which uses a PLL in source synchronous mode, but when I compile this design, the fitter says that PLL compensation is invalid and ignores it.

I don't have a clue as to why this is happening. My guess is that I may have to change some fitter settings.

Please help!
