Option Group Sets as Data Dimension

I have set up a simple Option Set Group (OSG) as a Data Dimension with Public access and ran Anaytics and Cleared the Cache. Per the manual, I should be able to see the OSG as a dimension when creating analytics but I do not.

I’m using v. 2.33.4
but also tried it on the latest Play instance 2.34.1.

The dimension is not available in Event Reports, Event Visualizer, Pivot Table or the Data Visualizer in either version.

Thoughts? TIA.

Update: I see a JIRA bug report for this here: https://jira.dhis2.org/browse/DHIS2-8729
