Noise from amplifier

Hi, I'm trying to understand the results from a very simple sim:

source - gain block - port

The gain block is set with NF=0.01dB, G=10dB and reverse isolation=100dB

Then what I'm expecting to see at the amp input, for a 1Hz channel, is:

from source: -173.826dBm
from the amp: -173.826dBm from the port -100dB (RI) = -273.86dBm

However I get from the amp -167dBm
Is there something I'm missing

Could you please explain?
