model architecture is not aligned with "google/flan-t5-small"

In original paper. "Small. We consider a smaller model, which scales the baseline down by using dmodel = 512, dff = 2,048, 8-headed attention, and only 6 layers each in the encoder and decoder"
But Google's actual implementation is
network.T5Config:
emb_dim = 512
num_heads = 6
num_encoder_layers = 8
num_decoder_layers = 8
head_dim = 64
mlp_dim = 1024
it is confusing.
