Discrepancy in AX Human Annotation Features vs Documentation

Hi all – I'm testing out the Human Annotation capabilities within AX, and ran into a discrepancy from what's shown in the docs. The first screenshot from the docs shows the ability to configure more than 1 label for an annotation tag, but in AX I'm seeing what's in the second screenshot: only "Label 1" and "Label 2", with no option to add more. Is there a reason I'm not able to see the version shown in the docs with "+ Add Category"?
