Troubleshooting Email Waterfall Bugs in Lemlist Campaigns

Am I the only one experiencing this bug? When I run an email waterfall, I always double-check the catch-all emails to confirm if they’re deliverable or undeliverable. After validation, I create a Final Email column. Even when I select this column in Lemlist under “Add to Campaign,” it still ends up adding an email address — probably because Lemlist finds the info somewhere else in the table. How can I prevent this from happening? These emails keep getting added and are causing bounces.
