If the predictions look Ok then you can ignore the rounding error message. A visual predictive check would be a good way to decide if your model predictions are OK. You say CL is small and V2 is large. On what basis of prior knowledge do you judge them to be small and large? Unless you have some good reason e.g. CL much bigger than cardiac output then it isn't usually helpful to judge the numerical values to be small or large.
