Rear wheel well liner

2012 speed3

Hi folks! Got a really simple straightforward question I'm hoping someone can help me out with. I recently had my car in for repair and I noticed when I got it back there's a gap in the left rear wheel well just inside of the splash guard. There is an extra liner in that spot on the right hand side. I could have sworn it did not look like this before. I've tried looking at parts catalogues and even asked the parts guy at the dealership. Haven't gotten anything conclusive. Is there a liner missing or am I just going crazy and it's always been like that?
Thanks all!

 

Looks like something is missing for sure. Look for bolt and clip connections. It's an older car so missing pieces are easily seen.
