clunk noise when I switch C to S mode

When I switch C (comfort mode) to S mode in a parking position, it makes a clunk noise, while it does not make any noise when I switch S to C mode. I asked about it in the dealership, they told me it is normal. Do you experience the noise whenever you only switch C to S mode in a parking position?

i heard it.
kinda make sense to me why it clunks tho.
when switching from C to S, gear actually changes from 2nd to 1st in parking position.
since it's downshifting on dead stop, it may clunk.

I'll try to give it a listen next time I do it, but if I didn't hear it before, I don't want to be paranoid and give me a reason to be worried.
