With that top row "Stick CA" selected in the Puppet panel, if you expand the Face > Replacements > Mouth section in the Properties panel, is it showing a '1' next to Mouth Group, Neutral, and Smile? I see your Neutral moth is named Normal, so just checking that the Neutral tag was associated for that, and would show a '1' (signifying one matching layer).
Similarly, if you expand the Lip Sync behavior, are all of the used visemes indicating '1' match?
If so, I might need to diagnose the puppet. You can export a .puppet file by selecting the puppet in the Project panel, choosing File > Export > Puppet, saving a .puppet file on your desktop, then sending me a shared link (via Dropbox, Google Drive, etc.) to that .puppet file. You can either post the link here or via direct message.
Thanks.
Ok, so turns out I didn't have (or deleted somehow) the Lip Sync Behavior property at all! I added one, and it works now (for the most part). Thanks for your help!!
