Ability Stars (HELP!!!)

I need some help please, I have recently discovered some ability stars that I made years ago for fm 13, I have attempted to place them into fm18, putting them in graphics/icons/stars like on previous games. i have done this for both the skin im using and just the parent folder but they are not appearing in game. has this location been changed since then and if so, where do i have to put them to get them in game. (p.s. not sure if i need a config file for this or not)

try to place them:

\graphics\icons\custom\star rating
