I've created custom icons for genres, top actors, and index icons, and they all work perfectly. However I've created icons for my custom categories, placed them in the right folder and named them appropriately, but when updating my Dune metadata MyMovies doesn't seem to recognise them and export them. I'm quite confused seeing as the others work but these dont seem to.

Is there anything I could have missed here? Any help would be great :)

Thanks,
Paddy
