Ellipsis 8 Oddity

My wife and i both have an Ellipsis 8 tablet. We both have set up our wallpaper for the home screen. When we access the app drawer, mine shows the icons on the wallpaper, hers shows the icons on white or a white card. Whats up with that. We've tried to set her tablet so the app drawer will show her wallpaper but we can't seem to figure it out. Whats up with that ?
