Strange reason to hard reject my item !

this item https://drive.google.com/file/d/1akDvlnbNdPPXJ4jtWhoLiWTNezGH5z2E/view?usp=sharing

has been hard rejected because there is pre-rendered 3d object and it is not editable !
I made the template so the customer can change all template colors and to add his logo and his slogan !

Really I can not understand the reason to “HARD” reject !
