What are the reasons for the incorrect operation results of Aspen simulation for gas methanation?

The principle of the methanation process is that CO, CO2, and H2 undergo a methanation reaction under appropriate temperature and pressure conditions in the presence of a catalyst; the chemical reaction equations are given in Equation (1) and Equation (2). CO + 3H2 → CH4 + H2O CO2 + 4H2 → CH4 + 2H2O. When I enter these two reaction equations in Aspen and proceed to the next step, an error message appears: Conversion is not allowed for a Component unless this Component is specified as a Reactant for the same Reaction. I don’t understand what this means Seeking advice
Specify the reactant as the reference substance for the conversion rate
Thank you, I’m using it for the first time and there are many things I don’t understand
