MIDI Guitar 2 plug-in for GarageBand is showing an unusual screen

1

The MIDI guitar 2 PlugIn for Garageband is showing an unusual screen! I am using a 2024 Mac Mini 2024, Apple M4m. The PllugIn shows the correct screen on a Mac Studio 2025, Apple M4 Max. Both running Sequioia 15.4.1. When calling up the Plug-In, the correct interface just doesn’t show up. HELP!!

I don’t use GarageBand but in Logic Pro there is a toggle between the parameter list (as you posted) and the full GUI. Is this option present somewhere in GarageBand’s settings?
