Question:

There has to be one submission record for one destination in Safety Vault. However, there are duplicated submission records created by the system like the following image. What is the cause?

Answer:

The transmission profile is updated after the rule evaluation to a different transmission profile. The system considers a submission a duplicate only if the transmission profile and destination both match. So, the duplicated records are created by transmission profile changes.
