XK-24 keys and Keyboard Maestro macros are offset - cannot even make new macro

Has anyone seen this?
Set up a new Macbook Pro for a user, migrated his KM settings.
The key assignments LOOK right in KM, but they are offset by a few keys.
Macros are fine when fired from KM
Change was from Mojave to Catalina. Scratching my head
When I make a new macro, clicking the X-key button registers the "correct" one - but the macro will not play afterward.

Hi @digisupport , welcome.
There are a few threads about XK keyboards not fully supported.
Might try setting it in a Windows machine first?
