Properties and classification set incorrectly in significant burst alerts

The kafka notices associated with S230808i, the first significant alert of O4 that only had a cWB g-event, were sent out with a bunch of links to non-public files in the superevent. These links were in the event.properties and event.classification sections of the notice, which should be empty for burst events. One example of a messed up notice can be seen here.

Update 1: It appears this only happened in the initial alert, not the preliminary alerts.

Update 2: This alert did not get sent via SCiMMA, because it didn't pass the runtime validation check used in the avro serialized messages. That resulted in this sentry error.
