Issues with Find Work Email (SMB) Waterfall Steps and Redundant Credits

Hi, we're having an issue with the Find Work Email (SMB) waterfall. Two things that are occurring:

1.
For some rows, it will run on multiple subsequent waterfall steps even if a previous step succeeded — consuming redundant credits.
2.
For some rows, the output column of the waterfall is empty even if an email address was found in one of the steps.
