HDRP- no shadows for default and enemy layer

Hey,
Shadows aren't showing up when an object is set to the default layer or the enemy layer. Shadow show up if I change anything else but then the player falls through the floor. Just wondering if anyone else has had this problem or knows of any fixes. I know that HDR support has an implemented yet but I'm just wondering if anyone's found a fix for this

Thanks,
Greg
