Update transaction group - not updating t_stamp

When I create a transaction group that just updates the first record in a table, the t_stamp field does not update. It still has the original date/time of the very first transaction. This is not how FactorySQL acted. Am I missing something?

EDIT: For now I’ve resorted to remapping the gateway date/time tag to the t_stamp field. It’s working. Kind of a pain though, considering for years in FactorySQL I didn’t have to worry about the t_stamp field.
