Calculated initial values NOT the same as specified

I have seen this now in 2 simulations... The initial values specified in Initial Value Domain nodes are NOT the Initial Values the solver ouputs, either at t=0 of the solution nor when asking the "Get Initial Value."

Is there a reason for this as the Initial Values are being changed dramatically when solving (i.e. half the value for IVs that had value, and non-zero for some IVs that were zero)?

Any help is greatly appreciated.
