The Order status of all the orders missing date_completed are flagged as completed and the meta key is missing. All plugins are up to date. The issues is across different versions, different plugins and different hosts. It becomes an issue when you are downloading financial data into an accounting system and the data does not match the reports. The question from the accountant becomes “If that data is incorrect, What else is incorrect? Which one is correct? The reports or API?”
I agree it is a small issue with only a few orders affected. It is difficult to track down what happened, but it leads to many hours wasted trying to figure it out.
