Cupboard underneath hob not closing.

[Kevthegas]

Evening, the left hand slider underneath the gas hob on my 2018 Cali will not close any further than this. Is there a guide which has broken off the runners? If I put a cable tie behind the catch the door will close so I know there is no blockage. I did find a small piece of plastic in the cupboard which I am presuming is stopping the door not to come forward enough and hit the keep ??
Any ideas, or photos of the missing part would be great.
