Suddenly Eyes Up-Down Dial Also Makes Eyes Crossed?

in The Commons
This is beyond me. It's probably because of something previously installed but now the "Eyes Up-Down" dial for the "head" part also makes the eyes crossed (figure is G8M). Is there anyway to check why this is happening and how it could be fixed? Is it because some scripts/morphes unintentionally linked the two dials (eyes up-down and eyes crossed) together?

Compare the Currently Used section of the parameters pane, with the option menu>Preferences>Show Hidden properties on, before and after using the Eyes Up-Down control.
Is it happening with the very base G8M? If it's a morphed figure, this can happen because of a morph with bad rigging that rotates the eyes' axes.
It seems to happen to every base G8M. So I guess it's not character specific.
No unsual activities are observed. Seems to be more related to maybe a specific morph. Will try to figure out which one. Thanks!
