[Freesurfer] lh.pial of fsaverage with topological defect

Dear FreeSurfer experts,

the lh.pial surface of the /subjects/fsaverage subject seems to have a topological error. When I load it (in Freeview or Matlab) I can see a small area with lower node density (and bigger face area; see attached). Is there any updated correct version of this surface available? Or is there a way to fix it?

I have a related question: the cvs_avg35_inMNI152 does not have this defect in the lh.pial surface. Is this the MNI152 atlas? Or is it different?

Thank you for your help, Sabrina Brigadoi
