Solidor adjustment

[Ashworth1]

Hi I purchased a door and fitted it 6 months ago. The door on the inside is slightly lower on the left (hinges are on the right).
This causes it to be very stiff. I included a pic of the hinge. It doesn't seem to be adjustable as there are 2 verticals holes and 2 horizontal so it doesn't allow it to go either way.
Has anyone seen this type of hinge before?
Regards

If the door needs to go up undo the horizontal screws and loosen the 2 vertical ones and lift the door. Should go up by a few mill.
If it needs to go sideways do the opposite screws

I loosened all the screws- won't shift as the thread is pretty much the same diameter as the whole.
Surely a bad set up ? I assume all doors need adjustment every now and then!
