FN2R Wheel arch skirt won't clip in

[fn2au]

Hi guys, I installed an Injen Cai on my car and after putting the car back together I noticed one of the clips isn't holding. I've tried to hit it in hard but nothing, it still holds it but when you compare it to the other skirt it looks a bit fatter.

Would anyone know how to fix this? The clips look fine.

EDIT: Does anyone know where I can get these clips? I've searched on eBay but they look completely different to mine.

Cheers
