Percussion part doesn't show 5 line staff

[Bert_Appermont]

I have set my percussion staffs to 5 lines in the lay-out mode which looks fine on the full score. In the parts however, it shows a two line staff.
How can I solve this?

Select the part in Layout options and set the same thing. On the right side.
