my one did this, , if the lower fog not fitted proply then it dont sit right, my ower fog was broken so swap it with a new on and now its fits fine

also theres a white bit that sticks out the slam panel, and if thats loss or tighted up to low then it wont keep the bumper up, best thing for u, is to remove the bumper and re fit it, might help
sorry i havnt decrided it well!!!
hop it helps!!
