AWS::DynamoDB::GlobalTable - Issues creating global tables with Provisioned BillingMode tables

When trying to create a global table stack without the billing mode it defaults to Provisioned or even whan I set it to Provisioned Cloudformation complains
that:
`You must specify ReadCapacityUnits or ReadCapacityAutoScalingSettings for each global table replica and each of its GSIs when BillingMode is Provisioned `

When I add either one of those to the template I get this error:
`TestDynamoDBGlobalTable with message: #: extraneous key [ReadCapacityAutoScalingSettings/ReadCapacityUnits] is not permitted` it's the same if I use the ReadProvisionedThroughputSettings key.

These docs https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-dynamodb-globaltable.html don't have them in the example but do have them on the dropdown options on the left hand side menu

I know I can set BillingMode to `PAY_PER_REQUEST` but wanted to know if this is an issue or if there is a way around it.
