When doing previews with kafka sinks, results in duplicate messages

[jevy]

What's wrong?

When building a stream and I press the eye icon to do a preview of the stream, after I create the job, the destination has duplicate messages. Tested with a kafka sink node.

Expected behavior

I would expect there not to be duplicate messages when the job is created

Steps to reproduce

Create a preview of a stream
Click the eye icon on a node
Press create job
review the raw messages on the topic.
Observe duplicates.
