AWS IoT TwinMaker with AWS Managed Grafana Annotation Problem - Unknown component type DataOverlay

I am working with AWS IoT Twinmaker and AWS Managed Grafana in eu-west-2 (Ireland) region. I am building out a WindFarm scene and I am attempting to add a data bound annotation. This seems to work fine within AWS IoT Twinmaker console.

But when I load in AWS Managed Grafana I get the following error:

Unknown component type DataOverlay.

I have also configured an overlay on a tag:

And I get the same error (albeit duplicated because I have both the tag and the annotation)

Has anyone got this working? Am I doing something obviously wrong or does this just not work!
