:O This is a strange problem.
Are you sure you exported all the markings in the folder to C: >>> Feralheart >> media > textures and replace? Also the markings.cfg to C: > Feralheart And replaced?
It sounds almost like you either have extra textures or missing textures. If it really bugs ya', uninstall FH and then reinstall it from this site. :3 Save any presets or markings ya' have.
