aspen dynaminc

After importing the already converged AspenPlus model into Aspen Dynamic and setting the required PID values, why can’t I obtain the steady-state results as initial values after running the initialization process? For example, when dynamics are first introduced, the feed rate is the same as in the steady state, at 100 kmol/hr. But after the initialization process is completed, it becomes over 30. What’s going on? It wasn’t like this before.
