Transposition using VEPro

So, sorry for my poor english but i have a problem
I try to make my own template using VE Pro, i follow the instruction of the notion video and everythlng turn well except the transposition.
For example, my clarinet was notated in C, so i go to staff setting and for "notated C sound", i choose : B flat - same octave - lower, hit ok, and nothing change, even when transposed in the view menu.
Can anibody help me please ?
