Parameter count formula for RWKV

[Triang-jyed-driung]

According to the formula at the arXiv article, the parameter count of the RWKV-4-world 0.1B model ($L=12, D=768, V=65536$) would be:
$$2VD + 13D^2 L + D(11L+4)$$
which yields

>>> 2*65536*768 + 13*768*768*12 + 768*(11*12+4)
192780288

But the output is

So, $2VD$ comes from

head.weight                       f32      cpu    768 65536

blocks.0.ffn.time_mix_r           f32      cpu    768

However! Where is $4D$? these are only $2D$:

ln_out.weight                     f32      cpu    768
ln_out.bias                       f32      cpu    768

Am I missing something?
