Updated mouth art and Lip Sync Behavior can't detect mouth shapes

I'm using a shareable puppet asset as a mouth chart so I can use it on several puppets. I revised the PSD file(kept same file structure) and when I change the file path to PSD, not only do I lose all of the behaviors-- but the top level Lip Sync Behavior no longer finds the tagged mouth shapes.

The mouth shapes are labelled correctly and are auto tagged correctly by CH... but on the top level puppet, the Lip Sync Behavior says 0 for all the mouth shapes. Before linking the new art, it had 2 instances of each mouth shape (an autoswap set for a happy and sad mouth).

I've also tried dragging the psd into CH to make a new puppet, same results. It tags the mouth shape layers but it doesn't show up in Lip Sync behavior.

I've tried this in both CH 2023 and the beta 23.3.0.38 -- same results. Any ideas on how to troubleshoot?

Thanks!
