[Freesurfer] white/pial surface in lateral ventricle

Hi, I was looking at some of my data and noticed that the white and pial surfaces occasionally invade the lateral ventricle (see attached picture). I went over to the bert sample dataset and noticed the same thing (coronal slice 87). Is this something I should be correcting or is it something that is ignored during the registration and labeling process? If I don't care about the choroid plexus volume, should I fill the white matter mask throughout the ventricle?

Thank you in advance, Mira
