Developer error? Orchestra 1937 Can't Be Repaired (Syberia: The World Before)

In my 1937 orchestra, the left pins are located differently - with the long end lower than in the short one - accordingly, it is impossible to tighten the left letters as it should. Is this a bug in the game?
Moreover, in Dana's drawing, they are also located the same way. The long left pin is lower than the short one. How to move it up???????
The xbox version of the game. I've tried moving them around but nothing works.
