Troubleshooting Email Waterfall Issues with Leadmagic, Icypeas, and Enrow

Hey everyone, just started building a clay table and i have a question... I have setup an email waterfall to find work emails with leadmagic, Icypeas & enrow as service providers.. i want to run waterfall from rows 1000 till 1100, if i right click on the column header and select choose number of rows to run, only leadmagic is fetching results and icypeas & enrow gets ignored if leadmagic fails to find email id. Any suggestions??
