This seems like an odd inconsistency, but on the energy Dashboard the gas usage is not reflected in the “house” circle.
This is likely since gas meters usually only meter cubic meters or other volumetric amounts of gas.
But according to my gas providers conversion, I added a kWh sensor derived from my cubic meter sensor.
But it’s not added to the kWh of energy in the distribution section.
So either the line connecting the gas bubble to the house bubble should go, or the gas used should be added if the sensor shows kWh, or added as volume if volumetric sensor is used.
