Aeon Artwork not transfered using USB-SDCARD WIZZARD


I want to clone my Aeon Nox build to another android box. I work using MAC OS to develop the kodi build. Has been successful back up and restore (transfer) my work using USB-SDCARD wizard from xunitytalk. Recently, I encountered some problems. My skin update (artwork) did not get transfer for any reasons, so I got just the default astronaut background instead of my chosen artwork. I can see perfectly in MAC OS Kodi. I have tried again and again, still no luck. Any thoughts or experiences?
