Headrest restraint guide in wrong position

[Deathinabox]

Hi, I’m wondering if anyone can help me solve a problem I have? There is a gap between the top of my seats and headrest restraint guide. Any ideas on how to fix eg cut down metal guide surround or if seat padding slipped down or has guide just stuck up? Need a why and a your best solution. Gap is about 1.5cm
Thank u
Put a picture in file if anyone wants to see the problem

Thank u I’ve decided to add a bit more foam to the top of each seat about 15mm that should negate The problem.
Cheers
