An additional integer-level completion identifies the charge labels modulo $k$ and has $k-1$ nonzero sectors. For even $k$, the two maximal labels describe one self-conjugate sector. This interpretation is specified in https://arxiv.org/pdf/hep-th/9410140[Dorey and Hollowood, section 2]; it is additional to the local classical density.
