John, did the label used to work for you? I know it did for me and my designer told me today they were confused because the module names were now all the same and they didn't know which ones they were editing.
I tried the syntax as described in Corey Smith's post, but that's not working for me. I'm using the "custom_widget" module in a custom-coded email template.
It would be nice to have another workaround or this feature added back in.
In the beta of the new Design Manager, it gives you the custom code for each module. It seems that Hubspot might be shifting to new syntax. I just tested this on one of my templates and had no issues at all. I was not able to reproduce your issue.
If this doesn't solve it, you might want to reach out to Hubspot Support
