It would appear that your fMRI volume is not aligned with your T1w image.

Peace,

Matt.

Leah,

I'm not sure exactly what was in your display. But I think what Matt was asking 
for was to see the surface contours for your individual subject surface (e.g., 
midthickness) overlaid on volume slices using the Vol/Surf Outline as in the 
attached screen capture (which is an average surface, but it suffices for the 
point).  That will help determine whether the surfaces you are using are 
aligned with the volume data used for the volume-to-surface mapping.

Dear Matt,

Please find attached 2 pictures of individual z-map on brain.finalsurfs and 
averageT1w_restore (template).

Much appreacition.

   What does it look like if you view the volume surface outline of your
   chosen surface on the functional connectivity volume in Connectome
   Workbench?

   Peace,
