Variaudio changes not audible when Group Editing

I’m writing some BVs by VAing a duplicate of the main vocal. These tracks are part of a Group-Edit (and I’ve made sure I’m using the correct visibility and layer-editing options) but all I can hear is the original line, even when I Solo either the track or the editor, although previewing the blob plays the harmony I’ve just created.

Turn off Group Editing and suddenly I can hear the harmony. Turn GE back on and I can still hear it but I’m back to square one as far as editing goes, i.e. I can’t hear any further changes!

I shouldn’t have to turn off GE just to use VA, should I? Anyone else seeing this?
