superpotential the expansion parameters come from both the $LH$ and Right Handed ($RH$) sectors. The expansion parameters, $\varepsilon $ and $\bar{\varepsilon},$ for the up and down sectors[^7] in the superpotential may differ as the SM gauge group does not relate the up and down right handed quark sectors. However the contribution from the $LH$ sector to the mass matrix structure must be equal in the up and down sectors due to the $SU(2)_{L}$ gauge symmetry. Thus its contribution cannot be larger than $\varepsilon ,$ the smaller of the two (right handed) expansion parameters. This implies that the Kähler rescaling matrix in the $LH$ sector, $N_{ik}^{L},$ has a strong hierarchy controlled by the small parameter $\varepsilon $ with $N_{ii}^{L}\simeq 1$ and $N_{ik}^{L}\leq \epsilon $ for the non-zero entries of the upper triangular form. Notice that the smallness of off-diagonal elements in $N_{ij}$ (and $K_{ij}$) is necessary in any model where the hierarchy of the Yukawa matrices is due to the presence of an underlying family symmetry, either Abelian or non-Abelian. This is specially simple in Abelian models where the hierarchy in the Yukawa matrices and CKM mixing angles is guaranteed by the different powers of the flavon field. Using a triangular
