Cubase 15 Expression Maps Not Working From Cubase 13 Project

Cubase
1

Opened up my current C13 projects in C15 and expression maps don’t seem to be working right.

They’ve translated ok to the new format, and appear to be set correctly in the key editor, and work if I trigger the key switch from the keyboard, but on playback it’s always stuck on the default articulation (and latch is ON).

Bug or something else?

Does it work if you remove the expression map from a track and the reassign it? If yes, it might be related to this: Expression Maps in Cubase 15 not sending output after external trigger
