The window sash is warped floor-to-ceiling, the door scrapes on the floor

Almost all of our new plastic windows have been installed without complaints, straight and adjusted. Only one patio double door (without a post, i.e., Stulp) has a problem:

During the installation of the dry screed, the planner (myself) measured and calculated a bit too tightly, so the distance from the bottom edge of the sash to the parquet is only 1 cm. In itself not critical, the floor is perfectly level without irregularities and the clearance at the sash hinge is also adequate.

But the window sashes are not exactly rectangular, but a parallelogram slanting toward the end, so that their tip scrapes on the parquet. This applies equally to both sashes. So the window is not hanging crooked in the frame, but the horizontal profiles are not perfectly perpendicular to the vertical ones. This can be seen with a spirit level, by the line at the floor, and when you look closely at the edge of the glass in the frame. Approximately 1 cm offset over 70 cm sash width.

The window fitter was initially punctual and neat, but at the moment he is very scarce (although a final payment is still outstanding; the seals that were mistakenly delivered in black are also to be replaced with gray ones, all material is already here).
In the entire house, these are the only sashes with this issue, I have checked them all again.

Can something like this be fixed? Removing the trims and glass and then loosening and tightening some screw connections or similar? Or do both sashes need to be replaced?
The door closes properly, but it cannot be adjusted upward any further because, due to the skewed sashes, the play in the frame is fully used up.

Don’t get me wrong, I don’t want to do the work myself, but just want to know how big the effort for repair is and whether the manufacturer needs to handle it or if the window fitter on site can.

In my opinion, he has to deliver new wings. How else should one correct that?

Take a photo, please?

Are the doors tinted dark on the outside?

Perhaps the panes were not properly shimmied....? To check, the window installer must remove the [leisten] and then you can see the shimming of the glass.

Could you take a photo?

I'll provide it at some point.

Are these exterior doors wrapped in dark film?

Ral 7047, telegrey, so not really dark, white inside, windows face southwest. I don't think it's due to thermal distortion, the sashes lie flat everywhere, only the profiles are not at right angles to each other.

Could be. When I search online, this exactly describes my problem, thanks! That should be fixable, especially since the window trims and glass have to come out again anyway, because the seals are in black instead of gray as ordered. ... Now I just have to get the window fitter to come around.

Hmm, if that isn’t a right angle, then I have to tear the entire door leaf apart. Bonded with MS Polymer. You could hang a car on that adhesive... then replacing it would surely be cheaper. Karsten

With our Schüco si82 doors, there are plugged strips everywhere that encase the glass. Once the panes had to be replaced because a stone caused a hole in the glass :-) Even the plugged strips had to be pulled out by the installers with great force. They hold plugged like hell. If they are glued, then no chance to open and close that without damage...
