missing schema for storage settings.voting_tag

Using 8.x-1.x-dev, created fivestar field via UI and then exported the YML, when include that with a custom module that creates a custom content type using a fivestar field it fails installation due to the settings attribute of the fivestar field's storage settings.
This is the exported YML file (minus the uuid):

langcode: en
status: true
dependencies:
  module:
    - fivestar
    - node
id: node.apic_rating
field_name: apic_rating
entity_type: node
type: fivestar
settings:
  voting_tag: vote
module: fivestar
locked: false
cardinality: 1
translatable: true
indexes: {  }
persist_with_no_fields: false
custom_storage: false

I also tried replacing settings with

settings: {  }

but the error is exactly the same:

    Drupal\Core\Config\Schema\SchemaIncompleteException: Schema errors for
    field.storage.node.apic_rating with the following errors:
