FiveTran connector for BRAZE represent bad data for MESSAGE_VARIATION and CANVAS_STEPS in target. Connector does track history for these tables similar to type-2 dimension change tracking but if a record is deleted that is not updated in the integration target. 

We request a feature to include _FIVETRAN_DELETED flag for these two tables so that active records are available at certain point in time.

Thanks.
