AB  - Recent lattice analyses of the Da scattering by Hadron Spectrum Collaboration(HadSpec) report only one pole in the Do channel. This is in odds with the unitarised chiral perturbation theory analyses, which predict the D0(2300) as the interplay of two poles. We provide an explanation for this contradiction - the existence of a hidden pole. We further show that the hidden pole can be better extracted from the lattice data by imposing SU(3) flavour constraints on the fitting amplitudes.
