                      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.},
