In this scene, the arm part you mentioned and the character's 'Hip' bone are connected using the studio's 'Node constraint' function. This may happen if the replaced character's body proportions are different from the original.
The shortcut key is [Ctrl+I]. After releasing (or deleting) the Node, adjust the position of the arm and then set the Node again.

Why is the arm position of the character incorrect when I am running the scene? The right arm of the left character and the left arm of the right character are incorrect :-(
