problem when I change driver names

Using for example , mod 1996 ..

I want change helmet positions .. (Hill - Ferrari / Schumacher - Williams ) ... and it's ok

but..

when I play non championship race... the name of the drivers don't change ... (Hill-Williams / Schumacher - Ferrari)

How can I do to have on the display the "new" driver name ? (Hill - Ferrari / Schumacher - Williams ) ?

Thanks in advance
