I just ran a simple waterfall work email enrichment on a table and am experiencing what I believe are some errors. Many of my rows are finding an email in an early step in the waterfall, but then continuing to search subsequent waterfall sources and using additional credits to find an already retrieved email. In many cases the email was found in an early waterfall step, but then it also found several times again in the steps ahead. This causes 10-15 credits to be used instead of only a few for the first source that successfully found the email. Also, many of these do not merge the email into the final column.
Here's a screenshot example. Something seems wrong here. Am I missing something?
