The scalar response is not counted again

scalar response is not counted again{ The term $-L_2{{\mathsf{E}}_{\mathsf{m}}}^{\mathrm{A}}f+L_1{{\mathsf{E}}_{\mathsf{m}}}^{\mathrm{A}}{L}_1{{\mathsf{E}}_{\mathsf{m}}}^{\mathrm{A}}f$ already represents the second scalar response. The new operation is the affine substitution $k\mapsto k+k_1[\varphi ]$. It adds $d_1[k_1[\varphi ]]$ once, not another copy of the scalar second-order pair.}
