I got this a few times before, although it was on the 737. But the same principle applies. For me it was a case of forgetting to hit the execute button on the FMC.

I had this problem over the weekend. Turned out that in a fit of slapdashery I hadn't entered appropriate fuel or ZFW figures in FS Actions. So it saw a discrepancy bewtween the imported perf figures and the unaltered fuel/ZFW figures. So lesson learned and worth doing things properly as you're supposed to. So you could add that to the list of already mentioned items as possible causes.
