[AVL-Fire Washcoat_UDR(WA)]

Currently I am using the catalyst model from the Aftertreatment module. In Washcoat's My_Reaction, I applied "User Defined Reactions (Without Archive)".My goal is to achieve the process of ammonia adsorption reaction.

NH3+ME_S1 = ME-NH3_S1
ME-NH3_S1 = NH3+ME_S1

When I did the calculation, the.fla file gave the following error:
%fire-W-at_inpspc_stoch, STOICHIOMETRY: Reaction 1 of monolith 1 is not balanced!
% Check coefficients!
%fire-W-at_inpspc_stoch, STOICHIOMETRY: Reaction 2 of monolith 1 is not balanced!
% Check coefficients!

Has anyone used this module? I have a problem and I want to ask your advice.
