Changes have been made to the Merge Field dropdown/pop-up. This change manifests the following problems: a) Multiple merge fields can no longer be highlighted and then dragged and dropped into the email editor. b) Export Definition nodes are not included in the merge field names; BBDM only displays the column header name. This means that Export Definitions with column headers named similarly can be difficult to distinguish between. This is especially problematic as pre-V3.0 Export Definitions are more likely not to have been assigned custom column headers.
