Hi 3dtester, I could be wrong but from your screenshots it looks like the right eye bone position is incorrectly placed relative to the eye - which is exaggerating the error when the avatar's eye is turned. I don't know if this is a conversion error or if there is some anomaly with the model itself - but there is a way to fix bone issues in CC3 - if you go the Modify Panel and the Adjust Bones, then select Face you can first visually check where the bones are, and if needed select and move them. It's important to have the avatar in default T pose and without any expressions applied when you do this - also it helps if the camera is set to minimum angle of view (as close to orthographic as you can currently get in CC3) and if the avatar is a base resolution, in wireframe. Please see screenshot - and I hope this might help -
