I am trying to group my line items by campaign but whenever I create a new campaign name, it automatically generates a new line item with just that campaign title in my empty/null cells section. If I try to delete that line item, the entire campaign gets deleted and my cells become ungrouped.
For example, if I link my calls called “Apple”, “Blood”, and “Clifford” to a campaign called “Red”, they are grouped together but the system also generates a line item called “Red” that appears in the null cells box and it won’t let me delete it without it automatically deleting and ungrouping Apple, Clifford and Blood.
