This response may be a bit off-topic, but I thought I'd add my experience.
I've also seen some strange behavior with predefined replies not showing up after created, though I'm not sure as the exact reason for this behavior.
I've resorted to managing my predefined replies in the DB directly. Actually, I manage the responses in a spreadsheet that I load into the DB when necessary. When I load them into the DB, I have to follow the following procedure in order for the updated articles and title to appear.
- import new values into DB
- modify/update one of the articles directly within
SS. This appears to cause
SS to reread the DB.
- reload my browser cache
Only after doing that, will the new articles appear in the menu.
