Loose side skirt on 2010 sport tech

Hi, I have just purchased my first MX5 2010 sport tech which is great fun. I have a few jobs to do on it. The side skirt on the passenger side behind the front wheel isn’t flush and sticks out about half an inch. Any ideas on what it could be, won’t push back in.
