Lior, Can you confirm that after you add the instrument to the score, it is actually there? Are you able to navigate to that staff? Simply highlighting the instrument in the dialog and pressing Enter will not add the instrument to the score. You need to press the add button, then tab to the list and make sure it's there. You can also reorder the staves there if you wish. Then press the OK button to return to the score.
