A global fit to the Cabibbo-favored (CF) modes in the $V\\!P$ sector gives many solutions with similarly small local minima in $\\chi^2$. The solution degeneracy is lifted once we use them to predict for the singly Cabibbo-suppressed (SCS) modes. Topological amplitudes are extracted for the $\\eta-\\eta'$ mixing angles $\\phi=40.4^\\circ$ and $43.5^\\circ$. The $K_S^0-K_L^0$ asymmetries in $D\\to K_{S,L}^0M$ decays denoted by $R(D,M)$ are studied.
