DV360 Bulk Editor Preview Missing Deltas

[sopwilso]

When 'Insert' ing a new Segment, or new Flight and Budget at Insertion Order, the 'Insert' row is not showing up when generating the Preview, yet is picked up when we load our changes, as a Success. Because it ultimately worked, this issue is likely deemed low-med priority, as users can always go to BigQuery to validate.

Reporting this following a ~2:40 pm cst deployment today to our production environment, which contained code fixes for previous Preview bugs, where deltas were not showing up.
