Nothing looks like it is wrong with that label. Can you verify that the white surface has not been changed since the label was created? Check how many vertices the white surface has with mris_info. The PHC label references a vertex index as high as 163798. If the white surface does not have that many veritices, then that could cause the problem.

Hi Doug,
Attached are the three labels I'm having an issue with (each with a different subject). These are built from areas that we found functional differences between a healthy control group and a MDD group. I was going to take a look at the anatomical stats to see if there are thickness or volume differences as well.
I am also going to review the white surface soon as Bruce suggested.

Rob, can you send me your label?
