I added a test item to the waterfall and now would like to delete it, but I’m not sure how to do it, the only button I see is “Add Line Item”.
As a workaround, I was thinking that I could just re-create the whole waterfall by uploading a CSV, but it seems that CSV upload is not overriding the existing Waterfall, but instead is trying to add only new items.
For example, when I’m trying to upload a test CSV where I have only 3 items: one bidding (Unity), one eCPM (Applovin), and one backfilling (ironSource), I’m getting an error that there are duplicate IDs (screenshot attached). But there are no duplicates in the CSV, so I think the system compares the existing waterfall with the CSV, instead of overriding it.
