The missing label is a very old issue that goes back to the original atlas, and I had asked the authors of the atlas about that along with a variety of other missing information. This missing region was noted by another AFNI user a few years ago. It appears to be "Cerebellar Vermis (10)" for the index value of 116. I don't have confirmation for that, but I can update the atlas with the additional label.
