How do I adjust the height of this UPVC door? (pics)

French doors, there is a small gap at the bottom letting the cold in, you can see the outside, so I want to lower the door a few mm.

I'm not sure what that small pin on the right does, I can remove it but it doesn't seem to do anything obvious. The big allen bolt on the left seems to just press up against the plastic below it, the plastic bit that the hinge rotates against, perhaps just holding it in place? If I losen it then it is no longer pressing up against that plastic but the door doesn't go up or down as a result. Am I doing something wrong? It's really getting drafty.

This method worked for me but you need to adjust all hinges a bit at a time

thanks lancs_lad but I need someone familiar with this particular door I think because it doesn't have the ways to adjust it like it shows there.

Its a Mila Evolution flag hinge, turn the allen bolt clockwise and as it pushes down then the main hinge body, the yellow arrow, slides up, it could be though that its already been adjusted to the max, check the gaps where the red arrow is, if theres a gap at the top but nothing at the bottom then its right up, the blue part doesn't move, theres 3 fixing screws that go through the main hinge body but still allow the yellow hinge body the slide up

That's brilliant, thank you so much.
It is raised to it's maximum height, as there is only a gap at the top, but that should be okay I think because I want to lower it. When I turn it anticlockwise, it moves away from the main hinge body, but the door is not moving down even when all three hinges are the same. Perhaps I need to josstle the door a bit as it's been where it is for a few years? Maybe place something ontop of the hinge and tap that with a rubber mallet to encourage it down?

Yes give it a tap down with a mallet
