My Dark Knight's eyebrows are bugged

I created this character model on the official server and wanted to use it on this server too. When I opened it in the character creator for the first time, the model looked fine, but when I opened it ingame the eyebrows changed the colour and shape. I can change it in the character creator, but every time I exit the creator and go ingame the brows reset to a different shape and colour. What should I do?
