What version have you installed?
v1.2.0 (web deployed) has a breaking change related to the metadata:
https://github.com/dtonon/manent/releases/tag/v1.2.0
(see the conversation about the NIP, too)
Wait, my fault! The web app was not been updated, it is stuck at v1.1.0 and I don't understand why it doesn't refresh correctly. Let me check.
