Payroll Flow Tasks show as successful but status not updating on flow

Summary:

I've created several flow patterns for our processes that require multiple submissions of the same jobs as well as subsequent jobs. For example - in order to process our off cycle quick pays, we need to run an archiver for both of our payrolls. Most of the time, these flows run through to completion without issue. Other times, we see that the task completes if we look at the logs, where everything says 'Succeeded' but in the UI it says it is still in progress and the only way to get it to finish is by force resubmitting the task.
