Some unknown name announcements do not work on Celia

[Boalbads]

Just tried to make an announcement created fully from unknown name stations, just for fun. It did not work.
Here is the link to try it: https://railannouncements.co.uk/stations/amey-celia-drummond/?announcementId=522a88b5-f619-4c57-82c7-d68b805e9110
Here is the event ID: 6620e59fe40649fda7a75dcf79638767
Here is the detailed information:
