Can you try an experiment for me?
cd $SUBJECTS_DIR/subject/surf
cp lh.sphere.reg lh.sphere.reg.auto # make a backup
mris_register -norot -rotate 0 0 +15 -curv rh.sphere $FREESURFER_HOME/average/lh.folding.atlas.acfb40.noaparc.i12.2016-08-02.tif rh.sphere.reg
Then run
recon-all -s subject -autorecon3 -nosphere -nospherereg
And see if that fixes the problem

ps. It looks like you are using a development of FS from Jan 11, 2020. In general, you should only use released versions

External Email - Use Caution
Dear Freesurfer Community,

I wish to manually reassign/edit cortical parcellation performed by FS.

We use the cortical parcellation done by FS and it has worked very well for most of our subjects. However, we have two subjects where the parcellation has not been done correctly. It seems that the central sulcus has been mis-classified to be one sulcus too far posterior in the brain - this has resulted in incorrect labeling of surrounding gyri. Curiously, it is only one hemisphere for both subjects (rh for one and lh for the other), where the other hemisphere is correctly parcellated.

In our two mis-parcellated subjects, how might we manually reassign or guide FS to correctly classify the central sulcus and thus correctly label the surrounding gyri?

I have attached a picture of an erroneous parcellation.
