Did he reconfigure the table mapping, and then the new table after renaming doesn’t replicate data?

CDC captures changelog based on table_id, and filters according to the filtering rules when synchronizing downstream. Since test3 was not originally synchronized, its changelog will not be captured. In future versions, changing a non-filtered table name to a filtered table name will result in an error.
