Transient and Steady state simulation results do not match

Hi

I have performed a two phase flow simulation both in transient and steady state.
Once I run it in transient apparently there is no problem and I can see the flow regime is kind of a plug flow with a lot of up and down, but once I try the steady state simulation the residuals don't reduce and it does not look like it is converging (I have attached the picture).
Does it mean that my transient simulation is wrong as well ?
