I was not able to re-produce this issue but the report is following:

"One more thing, I want to ask about the eyes, in the eye testing, for legacy, I put the correct names like "Head- Head, LeftEye- LeftEye" for blink I have Eye close L and R. So when I do create eye tracking, the eyes are.. kinda messy, like up is down and down is up, and left and right is.. going sideways instead if left and right.
Now whenever I do reset the right eye bone for some reason is using RightWrist instead of RightEye when I put it as"

I will look into this further tomorrow, however I think this maybe a rare bug which I might not be able to fix.

Further info from user:

Oh right, I have forgotten with it..
Okay, now that I have re watched what I have done.
1: Imported the VRM model
2: I've set up the visemes and eye tracking.
3: Now that may be of MatCombiner so, when I did MatCombiner that's when the eyes screwed up when testing them.

I was in Blender 4.2 and had latest update of CATS for that version aswell.

At first i did visemes and eye tracking and then i did mat combiner and when i did test them again they seemed broken as in the gif below, then I tried doing the following:
To export the same Vroid model again, then uninstall CATS and try it again, afterwards it seemed fine BUT I did MatCombiner first then set up visemes and eye tracking.
(The gif is how it was when I first did it the way I explained, it no longer doing this as far as I tested)

I have attempted to re-produce with no success, might be a rare odd ball bug. If anyone is experiencing this issue please add it to this report.

It has been discovered this is a material combiner issue as this issue only happens if you combine materials last, if you combine materials before setting up eye tracking this issue does not occur.

As this is not a Cats issue and seems to be a material combiner issue or some werid blender issue, I can not fix this, however I will add a wiki entry on the issue.
