This almost always is because the functional volume is not stereotactically registered to the anatomical volume used to generate the fiducial surface. Is this an atlas surface (e.g., one of the PALS mean midthickness surfaces), or is it an individual's surface reconstruction? If atlas, this could happen if you were trying to map SPM functional data to the AFNI midthickness surface, for example, because there are noticeable differences between those stereotaxic spaces.
If individual, make sure the functional volume is in register with the anatomical volume used to generate the surface.
