Ikea Metod 40cm kitchen cabinet with drawers assembly tips

Hello, I have a similar problem. I have managed to install all the drawers so far, but the top drawer is difficult to open and close because it rubs heavily on the metal at the top where the countertop is attached. The white metal has also already been scratched because of this. Why doesn't it fit? Where is the problem?

The bottom drawer already looks quite out of line with you. Maybe you haven't inserted it quite correctly yet? See further up in the thread.

The fronts were screwed to the wrong holes. There are 3 holes in the metal parts which I did not see.

Just a question... I used the wrong holes on the bottom drawer, so it is not flush with the carcass. How do I disassemble the drawer again so I can set the front lower?

If it is a Maximera that was not recently purchased outside of Germany:
