Datamatrix Codes with List&Label 21

I am attempting to add a Datamatrix 2D-Code to an existing Document in the L&L Designer.
Following the descriptions i found, it should look something like this:
Barcode("[some content here]",“Datamatrix”)
However, it seems like L&L 21 does not recognise “Datamatrix” as a valid type of Barcode. In fact, none of the 2D-Barcodes the help document describes are even selectable.

Are 2D barcodes not supported in L&L 21?

The 2D barcodes are only available in the Professional and Enterprise editions of List & Label. If you have a valid license for one of these editions, make sure the cmll21bc.llx is redistributed with your application.
