Flexing keyboard Latitude 7320

Good day. I have a question about the keyboard on the Dell Latitude 7320. I bought this laptop (P133G carbon fiber notebook version) for wife from someone who purchased it in Sweden. Compared to the previous series (f.ex.Latitude 7390), it is smaller, nicer, made of better materials, but less stiff, has fewer sockets and has soldered RAM. Is it normal in this model that the keyboard frame is very declassive and it bends a lot (the closer to the center, the more)? Is it correct that the keys in this model, when pressed, almost go deep into the frame for these keys? From what I have learned, this model can have screw-on or plug-in keyboards. Mine has a screw-on keyboard but after installing the inserted one, the problem was the same.
