What is the correct way to save adjustments to the G9 eyes?

Loaded a G9 character and made some translation/side-side/scale adjustments to the eyeballs (not the eye bones/joints). Saved the scene and reloaded to find that the adjustments were still shown in the dials but the eyes looked like nothing was changed.

Redone the adjustments and saved as a character preset, Loaded the character preset to find the adjustments showing in the dials but no visible change to translation and scale yet the side-side seemed to have opposite effect (making the character even more cross-eyed).

Finally did the translations to the eye bones/joint and scaled the eyeballs, no side-side applied. Then saved as scene subset. Loaded the scene subset and the eyes looked like what I wanted. No more cross eyes even though no side-side adjustment was made.

Why is it like that?
