Melissa, mine does this as well (silver model). I'm not sure there is a “fix" for this, but I try to just tap on the sides and shake the grinder gently after it's finished to knock out as much as possible before pulling the tray out. It's especially a pain when the humidity causes the grounds to go flying everywhere when pulling the tray out!
@Gerald Gerry Glaser, I’m having the exact issue. I believe it has something to do with the way the springs/steel balls are installed and I can’t find any guidance on how to correctly reinstall them. Very frustrating!
