Word class INM used to include more inflectional categories in the same tag (e.g. https://itwewina.altlab.app/word/acâhkos_êkâ_kâ-âhcît/ had INM < NA-1 + NEG + VAI-1). For relabelling purposes, we do want to keep only the first part (INM).

Eventually, we would also like to keep the extra information somewhere and present it, but without messing up the relabelling.

Long-term this should be changed, but we will just keep the first for now.
