I believe I understand the Op’s Question (and I’m not sure my answer is correct).
In GA6 when I load an Acoustic Agent Kit the related “Agent” i.e. Beat Agent, Acoustic Agent etc used to be shown at the top of GA6. Now, when you select a Acoustic Agent Kit i.e. Punch, Rock, Studio etc it shows that Kit’s Icon at the top of the screen rather than showing that it’s and Acoustic Agent’s icon.
I tried with Multi’s and single Kits but couldn’t seem to bring up that Acoustic Agent icon anywhere.
To bring some clarity here, in Groove Agent you have two types of Agents. Acoustic Agent and Beat Agent. For the Acoustic Agent there is the Studio Kit, Percussion Kit, The Kit, Rock Kit, etc. These Kits are different types of acoustic drum kits.
For the Beat Agent you’ll find different, genre-specific drum kits like you’ll find on a drum machine.
So technical speaking, it is named Acoustic Agent, not Acoustic Kit.
It’s not the Kit name displayed there, it’s the Agent name. Underneath, in much smaller letters, will be the preset name. The kit in this screenshot is The Rock Kit, with one of my own presets loaded.
