Technical Panel gap (boot-rear bumper)

[ZaphodB]

So I've noticed there is zero panel gap between the bottom of the hatchback bootlid and the top of the rear bumper panel section....... the bottom of the hatchback actually touches the bumper in the middle.

I took a look at another abarth and there is a decent gap, and if I push down slightly in the middle of the bumper I can create a panel gap.

The hatchback appears to be hung in the right place (as indicated by the rear lamps in the pics..)

So what could be wrong?.... anyone removed their bumper before ?.... is it not clipped in somewhere internally?
