[SOLVED] HALion instrument keeps reverting to piano

When I choose any instrument prefixed with [GM] in HALion Sonic SE, the instrument reverts to [GM] Aucustic Grand Panio. Non [GM] instruments do not revert for some reason. I never had this problem before I recently copied a project.

I noticed that the project I copied from has a different menu under ‘program selector’ in the inspector menu. All other setting seem to be the same.

Here is a view of the menu in the original, functional project…

And in the copied, dysfunctional project…

I fixed the problem by adding a new HALion Sonic VST instrument and deleting the old one. Seems like a bug to me.
