Additional details:

For logical replication, Fivetran lists tables that are not in the publication and blocks them. The sync mode is saved the first time the table appears in the schema, while it is still blocked. Adding the table to the publication later only removes the block. It does not apply the connection's sync-mode default.

If the default was changed to History mode after that first sighting, the table stays on Soft delete when the customer turns it on.

Apply the current connection default when a blocked table first becomes syncable, such as when it is added to the publication, if the customer has not chosen a sync mode for that table.
