CATIA V5-6R2016 SP3 - DMU Navigator - No 'Groups' button in DMU Review Creation 1

[tv9]

Hello,

I'm trying to create groups withing and assembly to ease hiding showing groups of parts in an assembly.

I have found examples online to do this via DMU Navigator, specifically the DMU Review Creation toolbar. However, the 'Groups' button is not available.

Currently trying to do this via a SPA-DMU SPACE ANALYSIS 2 Product.

Any help is appreciated.

I did receive a cryptic license error but when I go to License Manager it appears I have DM1 and SPA signed out.
