Issue with Waterfall Running Incorrect Sales Emails and Lost Credits

Hey, https://app.clay.com/workspaces/312137/workbooks/wf_c7gCaHG7GAE9/tables/t_yQA47cwJpaX8/views/gv_uwUtEb2TCosZ when I continued running my waterfall for work email it for some reason run me the Write sales email column which caused me to lose about of credits. I did a test with the first 10 emails, and I was not satisfied with it. And it runs it for around 200 contacts randomly. Why did it happen and can i get my credits back ?
