Isolated credit-order attributes still "pending" after several days

Could an admin have a look at submissions 250511-135019-981000 and 250511-135510-909000. I'm adding credit-order attributes and in each case the majority have been processed but one cast member is still pending: "Copsey, Michele Arabella 7" in the first case and "Gilbert, Derrick (I) Dick Woodiwiss 13" in the second. Does it just need more time, or is there a problem. I'm always intrigued when one isolated change gets stalled while all the others of the same type get processed immediately.
