Fix trunk hatch bumper

My trunk hatch rattles with a deep throaty boom when I go over bumps or the body twists.

If I cram bubble wrap where the pictured rubber stud slams into a plastic circle, the rattle goes away. This rubber stud is very loose and wobbles back and forth one quarter inch easily. Should I try to replace this rubber stud or readjust the trunk latch pressure or think about replacing the trunk weather seal?

Thanks for any ideas!
