Genre, Feature, and Classification ingestion terms are lowercase and singular. The “name” field contains the value as it will appear on the public site.
If you attempt to create a Genre/Feature/Classification with an ingestion term containing uppercase letters, those letters will be changed to lowercase. Likewise if the term is plural.
Use these ingestion terms when populating the “genres”, “genre1”, “genre2”, etc cells in the “products-default” ingestion template (and others).
