One trip (of two claimed trips) remained in "trips" for Agency A even after being claimed, and correctly copied over to sent trips. It was the last trip of 3, in which two were claimed and one was declined.
Issue shows that there is definitely concurrency happening within sheets operations. Solution was to reverse array, but we will have to be careful in the future figuring out what runs synchronously.
