uPVC door hinge adjustment - can I fix this draught?

[1SJC]

Hello,

We've got a couple of uPVC doors at the front & back of our house - both have developed an identical problem.

The door seal works perfectly around the door frame except around the top-right hinge, where a gap lets through a nasty draught.

I've looked online at several videos/resources and I'm struggling to get my head around A) whether the hinge style allows for the adjustment we need and B) If so, exactly which part of the hinge needs adjusting.

I've tried altering the 'mushroom' locking mechanism on the opposite side, but it doesn't affect the hinge side.

Is it possible to adjust the hinge so the door is pulled 'tighter' at the top right-hand corner?

Photos below - thanks for any & all suggestions.

If you take off the end caps, there may be a cam adjustment under there?

Would those be the top and bottom caps on the part of the hinge that's connected to the frame?

Yes

Yes

No idea what I'm looking for or if this image is useful, but this is taken from the top/looking down at the top hinge. Looking up from the bottom looks the same.

Ok, sorry, nothing there.
But I did miss this:

This looks to be the adjustment that pulls the door in.
Although I can't tell from the photo whether it is at its maximum adjustment?

Hero - that's the one! It appeared to be on max, but in the direction of pulling the door apart. Screwing it the other way has fixed the issue. Thank you so much, your help is really appreciated!!
