The subscription page only lists groups that are active and that contain at least one plan belonging to the current kitchen location. In addition, all plans of the group must survive the storefront filters — they must be active, not hidden, have at least one visible price row, and use an active portion size. If every plan is filtered out, the group vanishes with them. Check the plan's Group dropdown, its Is Active? and Hide Entire Plan toggles, and the Show to Customer switches on its prices.
