Particle-hole symmetry breaking perturbation in two-channel pseudospin Kondo problem is studied by the numerical renormalization-group method. It is shown that the repulsion between conduction electrons at the impurity site and the single particle potential are the relevant perturbations against the conventional non-Fermi liquid fixed point. Although the repulsion (potential) with realistic strength prevents the overscreening of pseudospin, it induces in turn a {\it real spin}, which is also overscreened again. Thus the {\it real spin} susceptibility becomes anomalous contrary to the conventional two-channel Kondo problem.
