Cubase 15 - Expression Maps Reset Keyswitch Positions to C-2 on Load (Migration Issue)

Greetings,

I’m encountering a consistent issue with Expression Maps in Cubase 15.

All my legacy Expression Maps (created and working correctly in Cubase 14) lose their custom keyswitch positions when loaded in Cubase 15. Regardless of their original setup (e.g. A-1 or even higher ranges like C4 for low instruments), everything gets reassigned to start from C-2.

This happens both when importing Expression Maps and when opening older projects that already contain properly configured maps - the positions are overridden on load.

What’s particularly confusing is that newly created Expression Maps in Cubase 15 default correctly to A-1, which suggests this is a migration issue rather than intended behavior.

Has anyone found a reliable workaround for preserving the original keyswitch positions, or is this a known bug currently being addressed?

Thanks.
