Eye glow doesn't work on player models ported from 3.3.5 to 2.4.3

[C8N_Christian]

Hello there.
So here's a problem: I have a private 2.4.3 server and I replaced all the player models with their counterparts from the patch 3.3.5a (for the sake of new WotLK barbershop hairstyles. Done by jm2converter).
They do work, however Night Elves, Undead and Blood Elves don't have their eye glow for some reason. Everything seems to be where it should, all the textures, models, etc.

I never had this issue with porting from 3.3.5a to 1.12. Or from 1.12 to 2.4.3.

Any tips for this problem?
I'm pretty sure it has something to do with the new geosets that WotLK models have, but for now I'm out of ideas how to overcome this.

UPDATE: Fixed by editing some geoset IDs with HeX editor.
